I have been told that a cam up to .540 lift should be okay but the only way to know is to check the fit with clay.

The lift of a cam has NOTHING to do with P to V clearance. When the valve is completely open the piston is at the bottom of the cylinder. P to V clearance has to do with ramp rates and valve timing.
