Which head gasket?
On an engine with a 4.530 bore which head gasket would you use? FelPro lists a gasket with a bore dia. of 4.540 and a gasket with a dia. 4.640. The first gasket seems a little small. Any gasket material in the combustion chamber will cause hot spots,detonation. But the second one is a little large. Which one should I use/

I am trying cometic this time around.
I have been using felpro for years. 4.540 is what I would run on 4.530 bore. Gerry |
Thanks

Cometics are hot right now. SCE also has a very good composite gasket. Gasket bore you need a minumum of .020" larger then bore.

.055" total is fine, .055" per side will leave to much area for residual contamination of continuing intake strokes. I am not a fan of the Blue gasket, I would check with Cometic or SCE. Do not recommend Corteco or the Blue.

I gaurantee you there is no play in the dowell holes on the Cometics!!!
They intentionally take some persuasion to get them on :D I'm running the 4.540 with the 4.530 bore per Cometic. |
Cometics are the ones to use. A little higher in price but well worth it.
|
Thanks. I did a search on Cometics and found them at Pfaff for a pretty good price. How thick are they.
