Default head gasket thickness/823-LS3 heads on 6.0

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.

Default anyone?

I dont want to spend the money to mill, I'm just trying to get the most out of stock heads, may as well build it with the thinnest reasonable gaskets. Still burning premium pump gas but would like to bump compression up to. Maybe I'm just "splitting hairs" and it wont make any real difference?

I have very limited experience with the ls motors, but generally, less than .035" piston to head, is too tight for anything less than a limited use race motor. .040" is perfect for a street motor. my .02
