Cylinder head swap on web site

I finally got around to posting a lot of the pictures from my cylinder head swap on a page on my site. I still have to do the A/F meter install and start on the chassis overhaul soon, since I have nothing under the car from the frame to the ground except jack stands at this time.

Mucho scraping, sanding and cleaning before the POR15 application, but that's for another post.

Thanks for taking the time to share the pictures. Any concerns about clearance with the shaved head?
 
Thank you, Bill.

Cyaker, the only issue is that we calculated that the original shop took of about .010" to .015" and I had another .080" removed for a total of .090"-.095".

If there were any more removed, I would have had to go to the shorter GT6 push rods.

Other that that, it goes like heck, no ping, no oil issues and now I just need to get the frame and suspension done.
 
Paul- could you do a TR8 head swap for me for future references? /bcforum/images/%%GRAEMLIN_URL%%/wink.gif
 
Paul, when you eat your dinner, do you separate your food on your plate into sections???

Nice documentation.
 
Paul - that is fascinating. I probably missed something - but what's the story behind the "rusted bolt [edit: stud]"? Did it "slip through the cracks"?

Any idea how the rust started there?

Thanks.
Tom
PS - that engine bay looks FANTASTIC! Bravo!

Actually, I do, but then I cover everything with gravy and mix it all up together before I eat it.
 
Did you do a compression check after the new head was installed? It would be interesting to know how much the pressures increased.
 
No, but when we do the retorque, that will be on the list of "to-do's". Good point, thanks for bringing it up.

I don't think that it will go up much, since I had no burnt valves and I don't think that having a higher compression ratio will actually raise the compression any higher than before. It could be an oxymoron.

Tom, I'm not sure and I wish that I had a better picture to look it over more closely. At the time, we were rushing to get it done so I could go to the British legends weekend the next day, so I didn't much forensic work with the time that we lost.

This is about the best that I can do for now, but I have the head in the garage and when the frame is done, I'll pull it out and look at the hole for the stud and the bottom surface of the head. The gasket did look good around the stud, so who knows?
