Are those 5.3, 5.7, or LS6 heads? If they have not been milled already then they can be milled quite abit assuming there will be no P/V problems with that cam.

It's a hard call to make because there is a LOT more that goes into p-to-v clearance than the max lift of the camshaft. What is the duration? Duration is equally important, as is the aggressiveness of the ramp profile. If it's large duration with a very aggressive ramp profile, then it could certainly cause clearance issues. The only true way of knowing is measuring with a dial indicator. This is how we check p-to-v clearance on all of our setups.
