Title: Head gasket question.
Post by: 482supersnake on March 08, 2022, 08:34:55 AM

I'm looking at Cometic heads gaskets and my question is on a 4.25 bore block should I use 4.25 or 4.30 bore gaskets?

I wouldn't think that the .025 difference in diameter would affect anything.  If you are planning on keeping the engine forever then go with the larger.  Cometic claims that they are reuseable so they would work with a future clean up boring.  They also have a head gasket kit that has intake gaskets etc.  Really not much more than the head gaskets themselves plus the other gaskets needed.
