Post 350 HEAD GASKETS

Alright guys lets work this out. A 87 chevy 350 bored 30 with 10.3 flattop 4 valve relief pistons - 20 destroked - I guess setting down in cylinder 20, and PRO TOPLINE vortec heads 64cc - 170cc runners,194 and 150 valves. What size head gaskets do I go with to get a .041 quinch remembering that the pistons have 4 valve reliefs. From what I read here the reliefs are about 6cc's. PLEASE help me out on this! THANKS!

yeah got you a set of good ol sucker pistons as I call them, cause most times, they don`t tell you they been chopped .020, to get a decent quench, you`ll need a GM head gasket .028, if the piston was already in the bore .020 and you add another .020 with the piston cut, and .028 with the head gasket, you get .068, and anything over .060 you loose power, I think Mr. Gasket may offer a thinner gasket, as well as GM may, but before I went with a gasket any thinner, I`d make sure the deck and heads are perfectly square. the slightiest bit of warpage and they won`t seal.
