2 valve relief flat tops with .015" head gaskets will put you at around 10:1 with Vortecs on a 350, so probably 10.5:1 or so in a 406- and with what some would consider a perfect .035 quench, which will make the chamber really efficient with less timing- which helps out with holding off detonation.
Head Gasket Thickness???
HOW MUCH OF A DIFFERENCE DOES IT MAKE
IF I USE A EXTRA THICK GASKET THEN HOW MUCH WILL IT DROP MY COMPRESSION RATIO.
