It depends on what size cam. If you want more compression you could go with a Cometic gasket in .040.

milled to what cc? what compression will you be at?

GM mls gaskets will work fine, or cometic .040 would as well... and with a better quench!

but either will work for you, I actually bought both when I did my H/C swap because I couldn't make up my mind..

What CR will you be at with stock 243s and cometic .040s?
