I hope I didn't settle for less?

Went to my 4th machinist today. I talked to the guy and he couldn't put in the teflon seals. He didn't have the cutter to do it but said he could do everything else. I had the Viton (Umbrella) type seals in my glove box as well so I gave them to him and told him to call me when he was done. Put bluntly, I'm tired of shopping. This guy was nice, sounded knowledgeable and didn't try blowin any smoke that I could tell. He gave me the name of another machinist who would have had the tool but I just gave him the head and told him to do the 3 angle valve job and mill the head until it was even and square but not to go over .010. My compression would have been at 8.9:1 without any milling and anything between 9.0 and 9.3:1 is fine with me. I have yet to find a machinist that has the cutter to put in those seals without charging me an arm and a leg. My thinking is that when I get the Head back and if I still want to put in the seals I can find a machinist to do it at a later date.

I take it your guy off Highway 9 couldn't do it? If you decide to wait, that will mean another head teardown though. There HAS to be someone in OKC or at least central Oklahoma that can do it. There is a performance shop on Flood St. in Norman that can do just about anything from what I hear. Can't remember the name right now though. They are just south of Robinson St. I guess that they get pretty backed up though.

I really like that guy, but I would never trust him with something like this...And yea there was a guy in Shawnee but he was so adamant that the Viton seal was a better choice...I just felt if he was a really good machinist putting in the teflon seals wouldn't be an issue. I know the viton seals will ride up some, but it will get me through 'til later. This guy is doing everything but the ts's for $130. He will put it all together for me, but when I get it back I will tear it down again and check it out before I put the head on, yea I am OC about that kind of stuff.

I was looking at my seals and my dad is taking it to 2 local machine shops that do all our work. Does anyone have pics of them installed? if they go in the way we think they do they need alot to be cut... Thanks, Tommy

Thought I would update anyone who is follwing this.. I took the bare head to the machine shop that does all my work and aparently they dont have anytihng to do the seals... so he recommended us to a place a little further away, they did it in a few hours and charged us a whopping 18 bucks! I will pick it up tomorrow...

Now I love stories like that.....Can't beat that with a stick...

so if you can post a pic! I'd love to see what I am missing.....

 

[hasa68mustang]

well I got it back today, I somehow got misinformed about who was doing ym head.. it was infact the guy that does all of our work (race engine/chassis builder) he has anice shop, builds a majority of the racers he races against in a circle track sorta deal.... today they were dynoing one of their engines.. and my dad said that I was HOPING for 120 hp and he thought my dad was joking... I doubt I will even be that high... Well I guess my dad had them just grind down the parts the seals go on (names not coming to me...) and it cost the 18 dollars... so we got all but 1 on sucsessfully installed... I guess he ground off part of the top to keep them from bottoming out from breaking or something... well my dad broke one... so we are in the process of ordering 1 or 2 to get this thing done... I took pics.. you can see my shiney new engine compartment... and umm my awesome gloves... now the pics...sorry for you dial uppers... if someone can edit the post to make the photobucket small clicky pics.... it would be greatly appreciated...





oops...

Nice, very nice indeed....I love pictorials. You really did open that log up..is that a E0 big log? Keep up the good work and give us some more updates as you go along.

Excuse me, another look and that is a D8 head. Man that log looks big compared to my D7 or is it just my imagination?

 

[hasa68mustang]

yes it is infact a D8, I could have planed abit more off to make it have a bigger surface area for the carb but the machinist didnt want to go down too far for he couldnt see in the hole and how thick the top of the log was. So I had to use jb weld in 2 spots, one of which broke off when we took the carb off which you can see in the pics (top left in the first pic), not a big deal...

 

[LameHoof65]

It looks very good, I was wondering how far the log could be opened up. I didn't get my teflon seals in, maybe later I will find someone who can put them in for a reasonable price.

When I was working in the machine shop many, many years ago, we used to install teflon seals on high perf heads. There were three things you needed.

First was the fly cutter. The seals sit over the valve guide boss and have to be cut to the correct diameter and depth. To do that you need the cutter with a guide the size of the valve stem. Not too many engines come with 5/16" stems, so some shops might not have them.

Second was very thin plastic sleeve that went over the end of the valve. This protects the surface of the seal as it goes over the edge of the valve stem. You can install the seal without it, but it may damage the surface and Teflon seals are not very forgiving.

The last thing you needed was the seal installer. This was a plastic tool that fit over the end of the valve stem and then over the seal. Then you simply tapped the seal onto the machined guide boss. Without this installation tool, it was very hard to put these on without breaking them.
