I was installing a set of heads on my car this weekend, and having all kinds of trouble getting the valve spring off the head. My question is this: If the distance the valve travels to the piston at TDC is 1.89", and the lift of my cam is .544. Is it safe to say that my p/v clearance for that valve is 1.346"? or am I just WAYYY of base here?
