Just wanting advise on head gaskets heres the problem.
Need to use .031 thick gasket to reach 11-1 comp . Not sure if this will cause other problems and does anyone know of a range of gaskets suitable .
THANKS

I know Felpro uses different thickness's but I am not sure about .31 thick.

I wouldnt use thinner gaskets, deck the block or mill the heads .010". Besides 10thou wont effect compression that much.

10 thou smaller will raise your CR about .25

All the fast parts catalogues I have show head gaskit thickness of 0.038-0.060 (0.040 average).

Normal Felpro is 0.041 compressed. Not sure where you'll get a 0.031

CRUSHU F150: 60 thou gaskits?............my bad!! Looked at the intake manifold gaskits column too.

Some serious dislexia looking at my parts catalogue.
