Default thinest head gasket?

What is the thinnest head gasket out there that will work with a 4.120"-4.125" bore?

Cometic makes them as thin as 0.028", however, you need to be mindful that you should have a minumum of 0.035"-0.045" clearance between your piston and head to account for conencting rod stretch at high rpm!

I would worry more on which is the best gasket. I use stock GM head gaskets. The cometics seem to leak and need to be retorqued down. I know you have a big bore so see what works the best. I would rather have an engine that is sealed verses trying to get a little more CR out of it.

The felpro gasket 1041 is .043 compressed and has a bore of 4.1 I think.

that FelPro sounds really good (the 4.130" bore)......if I go into Napa, I just ask for that number (FelPro gasket #1041) and I'm set?
