Well after examining my head gaskets it appears that I did a terrible job of getting the silicone in the right spots and literally missed half the hole in a few places. I also didn't scotch brite the gaskets to help the silicone stick to it. SCE has some copper head gaskets that are .032 thick so I think I'm gonna try those. My pistons are .016 in the hole and last years Summit copper gaskets were .043 thick so quench was .059. So with the 32's I'll be at a better .048.

I'm headed to Superformance right now to pick up some oil pan gaskets and show Greg my Summit copper gaskets.
