I've been trying to wade this whole thread - what a treasure trove of info - THANKS TO ALL!

Bruce, Paul, everyone - a great big THANK YOU!!! :thumbup:

At first, I was scanning through the thread trying to find price & availability of the SS head(s)? It wasn't long 'til I was up to my neck in the nut's & bolts ( make that "Over my head").

Well worth a small donation to PP - I wish it were more, but I'm now pushing $1K for my cam swap (and a few other "while I'm at it's").

I'm going to take the time to read through this again ( and probably again, and again) - more carefully. My eyes struggle to read extensively but they seem to recover under the shop lights so that's where I'm going... :wink:

In the mean time, if I missed the SS head cost & availability - any link would be much appreciated!

"Broncr" Thanks for your inquiry and you kind donation via the PP link to our cause.

Don't feel like the lone ranger when it comes to being overwhelmed by the information and nomenclature in this extensive post. I have to re-read several posts dated months back sometimes to comprise an answer.

Our new and finalized cylinder head names are SVO Jr., SVO Sr. and BSX-Flow Jr. being former SS or Street/Strip, Sr was former Max Flow U-head and the Cross Flow butt kicker is a welded 3-piece New Aluminum LS3 casting with 320CFM intake. All our (3) cylinder head offerings are NEW castings and will be bolt-on.

Tentative pricing for a fully assembled complete SVO Jr. head is in the $1,500 range. Your donation allowed us to break the $800 mark as I can now report we have received a total of $805 in a 4-month campaign contribution effort.
Here’s the PP link for those of you who may not be aware of our quest. https://www.paypal.com/pools/c/84uHkZRpXq

Still following along, though I won't be purchasing, at least in the near future. I too get lost in all the technical jargon but I learn a lot too. (Like the C8 head i have having smaller chambers)

I threw a small donation your way. I too am in the middle of an engine rebuild and it's draining the ol pocketbook pretty good.

Just got a call from the machine shop doing my carb head. He was able to get 210 cfm at .500" lift with a 1.94 intake valve. Just some data to compare against these new (better) cylinder head offerings.

Ok. Enough said. Gramps has publicly apologized, now lets all get back to this very pertinent and important thread about heads for our engines.

It only applies to commercial type ads and not casual, buy/sell items like cleaning out your garage. Soliciting services or parts on a commercial level is only allowed by authorized forum vendors. Also, using the forums messaging system to contact members on behalf of unauthorized forum vendors to solicite their parts or services is also forbidden. That has also been done by several members here. So, many of his threads have gone way overboard with violating terms and agreement policies starting with his first few posts. Many forums have these same rules and regulations, if he's breaking them here, he is also breaking them on others.

I'm going to unlock this thread for a while.

Gramps is doing VERY important work that is relevant to our Ford sixes, and he is not competing with any other head manufacturer on this forum.

Keep up the excellent work gramps. Any updates on when the first head will be dyno'd or available for order etc?

Many of us are patiently waiting to finally make some power out of our sixes and we greatly appreciate the work.

If I can make the suggestion a Facebook page or something is started so we can all discuss matters that risk getting this thread shut down or accounts deleted, elsewhere where it is permitted. Site rules are site rules, but fortunately we all have the right to go elsewhere.

Perhaps not.

However, you are the ONLY person complaining about this; to the contrary,I have had several PM's from members generally supporting this thread.

I am trying to walk a fine line here between strict interpretation of rules and keeping a very valuable thread open.

I intend to leave this thread open until someone higher up the food chain instructs me to close it. Until then let's keep this thread on topic.

Any off-topic posts will be deleted. That includes advertising and/or sniveling.

Bruce and I spent a lot of time discussing the start of this thread and where the boundaries were going to be.
The thread content was intended to allow everyone to be able to follow the development of all three heads and also be able to have some input on design features.

It was necessary to let everyone know that these heads would be available but that does not constitute a sale.
There has been nothing to sell to date and there are no specifics on pricing either.
When it comes time to bring product to market it will be handled appropriately.

Yes there was an oops on piston sales but that was quickly corrected.

The first 1.84"/160 valve junior head has been completed and is awaiting for the rest of the engine assembly for dyno testing.

We decided to begin the devolpment of the 1.94"/1.60" valve senior head.
A head is in the shop having valve seats and throats cut before starting the port and chamber work.

Now you can see just how a quality Ford OEM casting should look with consistent (wall thickness) throughout the casting. This will serve as an excellent guide for our** in progress** max flow SVO Sr head development. Yes we are getting there; hope to finalize our Sr. head design by years end so we can offer both Jr. & Sr. U-Flow alternatives in January 2019. We can now predict the Ultimate Aluminum BSX-Flow head will be finalized and ready for “field Testing” First Quarter of 2019.

That is the most informative sectioning I’ve seen. There seems to be quite a bit of available material in the sides to open things up a bit. Will you cnc port your runners or template and carve by hand?
Keep up the great work.

The old fashioned way, better known as eye/hand coordination. Right now funding is at a standstill for any non-essential program exploration such as cnc programing & exploration of available (cooperative) 4 or 5 axis alternatives. As our customer demand and distribution of our 2 EFI offerings [SVO Jr and SVO Sr] begin and are successful then we will be able to plow back any profits into automated cnc production with its inherent labor intensive savings. At least that's what my pea-brain dictates.

Every once in a while someone will ask “ how much can I deck the head?” Well fellas here is your answer. Bruce measured an average and fairly consistent deck thickness of .370”

Also note the powered metal rod that did not hold up to the turbo charged 600hp.

Gramps should have clarified, rod is not out of a Ford Six but Turbocharged Beemer just happened to be on the bench and as the post made by Wesman states

Also note the powered metal rod that did not hold up to the turbo charged 600hp no mention of Beemer and or 240/300 six. Not Wesmans error mine. :bang:

Having watched the progress & hoping for ~15 years, it's great to see the reality of better flowing 300-6 aluminum heads finally about to come to fruition. I'm saving my pennies. I'll admit I have become a bit lost in all the back & forth and am just hoping I can adapt one of these for my application - a 1982 carb'd 4x4 Bronco beast/mule. On my last build I did just about every conceivable improvement "recommended" FSP mod, short of larger valves. From unshrouding the exhaust, moderate porting & port matching to Clif single plane (with a 390 Holley) & FI exhaust, Walker Y, BBC rollers w/7/16 threaded studs, Cloyes adj gears, ARP studs, HE pistons, Zero deck, full balance, a mild cam, hi-flow oil pump - the list was about as extensive as "everything suggested at the time" ( about 10 years ago). I found a T-19 (out of a late 80's 6.8 diesel, with the sychro'd 1st), and even stuck a Gear Vendors overdrive in it, to get 7 forward speeds.


If someone could direct me to a full summary post (or two, or three) of the new head offerings - Primarily I'm wanting to know if I'll have to rework/change the rockers/studs. I believe the U-flows will accommodate a stock(ish) Cliff intake, and hopefully be drilled to better accept/secure the FI exhaust upgrade ( for my early 80's app). There are just so many iterations of the 300, over the decades, that I can see some potential issues for my particular situation/build. The need/desire to come up with a "generic" head that covers so many different applications - all the work involved is much appreciated, and very commendable. At the same time, I'd rather not do too much "backing up " to move further forward ( with the Ally head upgrade).

My apologies in advance - the answers are likely already out there, somewhere - there's just quite a bit of alternative/related discussion that is easy to get lost in. A final suggestion - I think they should be called, respectively, the "Thunder, Lightening, & Crossfire Hurricane heads - Jr & Sr, etc., just doesn't have same "appeal"... :wink:

The two new "U" heads will except any bolt-on items that you are using presently using.
They have the 3 extra bolt holes for the EFI exhaust manifolds.

If you are using rocker studs you will need pushrod guide plates and pushrods that are hardened for guide plate use.
The advantage is you can use 3/8" pushrods without having to machine the head.

The Scorpion pedestal mount roller rockers are a bolt down installation but may need shims to have the correct geometry with the longer valves.

For the moment the SR head appears not to need raised ports for increased flow but that has not been finalized.

The crossflow head needs the top of the lifter gallery in the block notched for the pushrods since the pushrods angle out instead of in for the stock head.
A custom lifter gallery cover will be supplied.
The pistons will need some valve relieves.

Any of the LS3 valve train components will work

Primary header tubes are 1 5/8" minimum. Will need to be custom or modified LS.

It is possible to adapt 300 six intake manifolds but would not be a good choice. Creativity will be needed here.

Thanks so much, Paul. It sounds like it will be relatively painless.

The "head fund" is growing...

I think I read somewhere here that there is a way to get on the "wait list"?

Edit: I'm sifting back through this thread from the start. What a ton of info - I keep getting sidetracked in my thought process. I'm almost half way through, this time. Many thanks to all who are sharing their thoughts, insights & efforts!

You can see above I quoted Paul's excellent post answering most of your questions but forgot to post the following last night hey even Gramps screws up occasionally. this should also help address your key points:

Thank You Paul your summary is dead on as usual and members of this forum has no idea how important your role is in our development program and its lofty goal progress. I also want to personally thank Wesman07 (Wes) for his consistent follow-up with Forum members who request additional information about one or more of the three cylinder head offerings. These behind the scenes efforts help motivate and guide us toward offering what you as a Group want and not just what we perceive to be the Big Six performance latest & Greatest. Progress is being made on all 3 head options. Luckily a few local businesses have donated work space, used tooling, interim storage for program essentials such as our new horizontal band saw with its 7” X 12” throat capacity. We now have a laser guided 15 speed floor drill press with 6” X and Y cross feed machinist vice not a mill but handy for some of our fixture work. Some extra curricula networking by Gramps has unearthed a neighbor who owns one of the premier machine/specialty tooling shops in the Chicago environs and has offered and will make any of our one-of a-kind prototype essentials. This goes to support the proverb which states “there’s more than one way to skin a cat”.
Gramps has been a little under the weather lately with a bout of Shingles which I wouldn’t wish on my worst enemy. Sure has altered my hectic pace somewhat but still manage to keep on truckin. Good news is I have had more time to contact old friends who have not been aware of our Big Six program and/or my personal fundraising effort thru the PP chip in URL. ‘Gramps’

Thank you, and best wishes for a speedy recovery.

I've known a few folks who've gone through Shingles. All relayed how horribly painful they are. One said it should the name is very misleading - it should be called something like "Non Stop Hornet Attack".

I got the Anti-Shingles Vaccination as soon as I was eligible. IIRC, one had to be at least 62, and it only lessened the chances of getting them.

Again - best wishes.

Important Update from Gramps

This post will be filled with mixed emotions both good and sad news, let’s get the sad news out of the way first.

Background:
For those of you who have been loyal followers of this Big Six development thread, you will recall that one of my First quarter mile success stories was centered around the very controversial and infamous Preparation H Maverick that was powered by a 300 Ford Six with a extensively ported 240 Ford u-flow sporting 3 48MM IDA downdraft weber carburetors.

When the Maverick 1ST hit the Division 3 and NHRA National events in 1970, I was still working in the Ford Performance Events Dept where employee competitive racing was a no no as it was then considered a conflict of interest. Ironically GM and Chrysler encouraged and supported their motorsports departmental employees and their racing endeavors were viewed as an avocation in contrast to Fomoco policy. The Preparation H Maverick made its debut at a Division 3 points meet in the spring of 1970 piloted by Tom Schumacher who was a Ford Stock eliminator driver regularly campaigning his low 10’s , very successful A/S 427 Fairlane.

The three silent partners of mine in this venture were Frank Pryg, Bob White and Art Keyes. Bob was best man at my wedding a very close friend and his two sons Bobby and Kim are going to field their newly constructed ‘cloned’ version of Preparation H using our Highest Flow U-Flow Sr head and making its Michigan ¼ mile debut sometime in 2019.

All the foregoing was necessary and I can honestly say I would not be involved in this program AT ALL had Bobby & Kim not bugged me to build them an engine for the past 3-4 years.

I had to make an unplanned trip to Michigan last Friday to see Bob Sr for the last time as he was not expected to live more than a week at most. On Saturday, I spent hours at his bedside viewing his emaciated frame, holding his hand trying not to cry and encouraging him to relax and let go. He seemed to respond to my voice at times and passed away peacefully at 2AM last Sunday morning.

On my flight home I promised myself that I would devote even more effort to our development program, as a tribute to this dear friend and his two fine sons; what better way to forge ahead to our Forum finish line. I ask of all followers and Forum members to “Keep the faith”; say a prayer for Bob Sr who is now in God’s hands, and bless the White family in their struggle to cope with their loss.

I will be posting significant program changes and developments by this weekend or next Wednesday at the latest. As always you can PM me, Paul or Wes with any specific questions you may have regarding any of the (3) [soon to be available] unique cylinder heads.
Warmest Regards, Bruce Sizemore

Thanks everyone for you kind and encouraging comments regarding the loss of my partner and lifelong friend Bob White Sr.

As we move forward on our 3-prong development program I have decided to take complete control of the BSX-Flow aluminum head and will be doing all or most of the hands-on fixturing, template work, welding fixture design and assembly, in fact everything short of the actual welding process will be my responsibility to see through to completion. I can't just tell someone what I want done for two main reasons, COST and on-the-fly changes will be much easier to control if I don't rely on others. May sound a little pompus but what most of us should care about is results and not how we get there. I will be asking Wesman07 and Paul (PMuller9) to update all of you as pics and progress are being made. BTW the Jr u-flow head is ready for production and the Sr u-flow is still in the port development stage but progressing nicely. Keep those thoughtful donations flowing we are idea rich program but cash flow poor. Gramps

After recently buying a '68 F100 with a 300 auto, I started searching the internet for info. Reading through this particular thread got me motivated. I first made a small donation for the work on the heads and then I joined this site. I am not wanting to build a 300 race engine, at this point, but it would be AWESOME to tow my Lightning to the drag strip with my old '68 300 6 cylinder. Not trying to alter anything on the thread but wanted to let you know you are motivating folks and I wanted to hopefully keep you motivated. I fully understand what it is like to stay motivated on an expensive, long term, race project. This is something that hasn't been done before so it is truly groundbreaking. Keep going guys.

Maxtrux: Great logical thought process, your positive attitude and support is a welcomed jesture for all of us involved in this complex undertaking. We will try and answer any program questions from our perspective but want you to know, as a newcomer, there are plenty of forum members with a wealth of knowledge to address most anything Big Six performance related. As we move forward we are already considering how best to work in Turbo & Supercharger usage with all 3 cylinder head types. Keep in touch. Again thanks much for the thoughtful donation.

Subscribing. Want to show my support, interest and appreciation in this head development project. Have read through these posts for the past 6 months. Very interested in a better flowing head for turbo app. Thanks!

I’ve seen where just two 5.3 LS heads were put together. With the smaller chamber of the 5.3, the fabricator centered cylinders 2&5 and said the rest of the chambers aligned well enough.

Using a head with larger chambers and larger valves, the .080" difference in bore spacing requires a 3 piece head.

Looking at that picture, I only see one seam and it is in the middle. Perhaps that’s the difference between what most people would try, and what you and Bruce are working on. One is a “permanent solution “.

On that head it’s just one seam. It’s not perfection doing that way, but for someone doing a “one off” themselves, it’s less cutting, machining and welding. It’s another interesting adaption of the LS head. Even that LM7 head with its smaller valves will kick the crap of most OEM pushrod heads...

How much would it cost to make the core boxes and cast the 6 cyl head based on Gramps welded up LS head?
