Could you clear this up for me? I’m missing what you’re trying to say. The cam your running has a valve lift of .500 because the .050 is confusing me. The stock rocker arms are not known to be very accurate at there listed ratio of 1.5. Normally less.
I run those pistons at a zero deck height and a 1.6 rocker arm for a total valve lift of .574. Up top? I’ve had Edelbrock heads, ProMaxx CNC heads (Edelbrock knock offs) and it currently sports Trick Flow heads. I hope that helps.
