Compression

On the pistons.. I'd rather have the rings down a little and zero deck than have the dead gasket space around each piston for liquid fuel to get trapped and cause problems (detonation starts in such areas). The head gasket is aband aid.. Truthfully, any future build would have the block square decked anyway... So the pistons are not unusable. Just a hair shorter.
On the cam, yes, I'm talking about something in the area of .580-.590 lift or more. Because (a) the heads flow well up there, and (b) the lash and angles take away about .040" of lift on a solid flat tappet. With the 11.2 you wont have any issues with a softer low end power level...lol.
