4 lip (double end) end mill here. The 500 rpm seems slo but depends on speeds'n feeds (of course).
Some 'hand feed'. Others 'automatic table'.

I hand fed it. And mine was 4 flute. I was amazed at the surface finish, it was so smooth!

Got the adapter angle milled today. I got it roughlt to 3.5°. It's definitely closer than it was flat milled. Next is to drill the holes into the head. I brought my junk valve cover to make sure it all fits on and allows me to take the VC off if needed.

Then i got to get studs and test fit the carb to make sure the butterflys move without obstruction. Im excited that its almost done!

What I'm happy about too is that its all documented here so others can see what I'm doing in stages so hopefully it makes it easier to see what is needed to be done.

Thanks guys for all the advice so far, keep it coming,
Ryan

I finally finished it guys. All thats left is filing a few spots that intrude on the intake area and sealing the surface in between. But I'll seal the surface after I get it magnafluxed and all the other head work to it.

Also i made a cover for the EGR valve spot. I'm thinking about drilling and tapping for a vacuum source there, or should i leave it as is? I don't really do anything for vacuum other PCV and my vacuum gauge. But i may add power brakes in the future, I'll decide that after i get my disks on.

So I've heard to use the aircraft grade permatex or to use 1/6" gasket material, i need to decide on that next. What is the poll on that?

Thanks,
Ryan

that really takes the cake (proof is right beside !).

I C in 1 pic another adapter below, yes?
Do U have a shot of that to look at?

Is top adapter so thick to get the carb links above the V/C?

Thanks for showin all the pic!.

Haha i thought the cake was a nice touch lol.

The adapter below is my cover for the EGR spot since i wont be running that. If you really want to see that stand alone i can do that for you.

No it is not. The throttle linkage hits on the low side. I need a 1" spacer to clear the log. I ordered one off eBay even though i could make it, but its time i actually start doing the assignments in class instead of this haha.

In your tuning experiments remember that on a street only car the EGR valve is quite useful in helping you to get the best in MPG. Plus since it's only operating at the higher hiway cruise speeds it doesn't really have an effect lower speed power. Good luck :thumbup: :nod:

I'll be using headers so i can't run one anyway.

You have done a very nice job!
On the gasket thickness, the flatter the two surfaces are the thinner it can be , and the thicker you go the more distortion you can have when tightened down...How thick is the gasket between the carb base and the body of the carb...It should represent the adapter to manifold surface.
At the top edge of the adapter is it the same size as the carb bore or a touch larger and not smaller?

Thanks man!

So everything should be very flat. I ran the mill over all my machined surfaces real slow to geg them all real nice and smooth. So my gasket should be similar in thickness to the carb gasket?

The ends of the slot fit the carb perfectly. The width of the slot is slightly larger. Why?

That will be just fine...If the hole in the adapter was smaller than the carb bore it would hurt flow and could be tapered.

but we have covered it here several times (quicker to hit google
for me than use "Search" here).

I C this and other engineered systems stripped off in their effort to customize their ride.
It may B better practice to research the motor function when completing their wrk. I will
assemble a 'closed PCV' system. I have 2nd thoughts with the 'adjustable' pcv (I believe it wuz)
Cat posted abt back awhile ago. I havea lill more cash for the project now and will B researchin it more.

I know about bent ears, my 2100 had bent ears and i had to mill it flat. I mean i can look at getting a thinner material. I'll see what they have for gasket material. Otherwise I'll stick to the spacer to carb gasket thickness.

I made a big deal about the slot being the same size as the carb, or larger. I didn't want any restriction as the point of this conversion is to let the head breathe more. I have a couple of very small intrusions but I'll clean them up with a file.

No the EGR doesn't restrict or cause un nessisary back flow. When you look at how its designed you can see it's not going cause a restriction, it introduces inert exhaust gas into the intake system only at steady state Cruising Speeds of 45 MPH or more this allows a leaner fuel mixture to save fuel. Yeah many people believe "emissions crap" lowers power and reduces Gas Milage this isn't nessisarly true especially for most street use cars. There is a level of all out high performance were it can start to be a henderace to power and of course there's the cosmetic looks. Good luck you are doing a great job on your build. :thumbup: :nod:

Alright guys, the head got dropped off at the shop a bit ago and it got hot tanked and maged, it all checked out. The guides are shot so I'm gonna get a complete valve job.

Guides
Valve stem seals
New VI port flow stainless valves
Up exhaust to 1.5"
Schneider springs/retainers to match cam

The valves are ordered and should be here next week some time.

I know I need to look into backcutting and 3 angle valve job. I will ask when I get the valves to the shop.

Anything else I need to look into? I have the book but I think besides porting I'm good. If i port, I'll end up doing it to the exhaust side and I'd just smooth everything out, nothing crazy.

Thanks,
Ryan

4 lip (double end) end mill here. The 500 rpm seems slo but depends on speeds'n feeds (of course).
Some 'hand feed'. Others 'automatic table'.

I did it all hand fed. It was a bit slow but it ate through it perfectly. There was no chatter or anything. Like cutting through butter

Milling Head for 2bbl

Post #78 by chad » Mon Oct 07, 2019 2:20 pm

its amazing isn't it? Chips fly like wood chips from a hachet...
Other times U get the 'curl'...
We hada 'shaper' It hada ram (like a broach but repeditive). The tool post helda cutter like one ona lath but 4 Xs bigger. U put the wrk piece (a big hunka metal) in the vice & the ram arm holding the cutter woud travel several feet then into the piece and shave offa hunk.The whole floor would shake. These were plank floors (boards 6 by 18 inch, 30 ft long) in 200 yr old machine shops - so that shaper wuz my fav.
:shock:
:lol:
