Has anyone ever checked piston to valve clearance on the 420a
with high comp pistons and high lift cams. My brother and I just took the head off his engine and we could see damage to the pistons from the valves hitting them. I was just wandering if anybody checked piston to valve clearance with a setup like this.
wiseco 10.5 pistons
crower stage 3 cams
crower valve springs
1mm oversize valves
