What I would be conserned about is quench. To make the most power and prevent pinging you need to run about .035" quench +/- .005 depending on who you ask. Quench is measured from the top of the piston to the bottom of your head. I milled my block to allow the pistons to stick out .004" with a .041 head gasket it comes out to .035 quench. You need to allow room for the parts to expand and bearing cleanances, so running less becomes more risky, running more quench is more likely to cause pining because your not creating as much turbulence that helps cool hot spots.
