I was told by my engine builder that the LY6 cranks seem to be better machined, and have some differences in the oiling holes and what not. lol I am no expert but I take their word for it.
I have LY6 crank rods and pistons with L92's heads(LY6 comes with L92's) all on a 6.0L block. Yes I did switch it to a 24 tooth also.
agiain let me know.

lift has little to nothing to do with PTV issues. when the valve is at full lift, the piston is near BDC. longer duration, tight lobe seperation, and a faster ramp rate is when you start running into PTV clearance problems.
