5.3 ptv clearance.
I'm wanting to swap the dished 5.3 Pistons out for 4.8 pistons. I'm running ported 706 heads. I have a MS3 cam on the shelf. I wanted to know if the ptv clearance is good before I start looking for a set of 4.8 Pistons. I don't want to waste time and money to find out the valve is trying to make love to the piston.
