Hello, Iron 6.0 block with LS2 rotating assembly (stock flat top pistons) and #823 heads off a stock,crate LS3. I have a cam spec'ed with stock .054 gaskets, at 10.36 compression. I am now thinking of getting thinner gaskets to squeeze a bit more compression. BUT...stock ls2 pistons poke out the block @.009 as measured and how thin a gasket can I go before killing the "quench"?......or hitting some thing? I plan on redlineing this @ 7100rpm.........such as .035 gasket minus .009 thou only leaves .026 thou clearance. Should I just stick with stock .054 gasket or mill the heads? I will check but I think my piston to valve clearance will be O.K.
