400 sbc head gaskets.
Hello all. I have a sbc 400 .040 and it has a blown head gasket. Does any one know a good head gasket for my engine. It is .040 over and I am running aluminum heads with steam holes. with 9:1 flat top pistons. Most of the gaskets I have looked up say they are only good for up to 4.155 bore, and I am at 4.165. Thanks for any info. Jason.
