The KB237 piston should get you close to zero deck. I think those pistons are 0.020 down in a blueprint block. Zero deck is a suggestion not a strict rule. For aluminum heads I usually build engines with the pistons 0.005 down and then use a 0.036 MLS (Cometic) gasket.
So if I wanted to build it like yours I would need to square deck the block 0.015? I'm sorry just trying figure this out.
