I measured P/V clearance using the drop valve method and a "solidified" lifter.
Exhaust .069
Intake .089
Head Gasket installed.
1978 351W Block
Brand New DSS Flat top Forged pistons .034 in the hole.
Brand New AFR 185cc Heads
Ed Curtis Cam
Very dissapointing, but glad I checked. I had to advance the cam 4 degrees in order to get it within spec on the cam card, could that have made a difference?
What now? I'd rather buy thicker head gaskets than flycut these rather expensive pistons.
