This cam really can't be "degreed" in. Many builds use a limiter anywhere from 6 to 22 degrees. I believe stock is around 60 degrees. So this is not like the old days where the engine has a solid gear and some offset bushings to give me the builder +/- a few degrees. I don't know every possible bolt, gear combination available for this engine, but realistically nobody is doing a degree with the cam. I could be wrong, but don't think so. The Cam Motion solid gear, single bolt cam upgrade will run at least $800 above the cost of just putting a limiter in the stock cam gear.

I built my motor mounted the heads temp and visually check piston to valve clearance (there was a LOT), I have a "low" lift cam and my pistons have large valve notches in them. If I had more time I would have checked the piston to valve clearance with the stock pistons just for grins.

Nutshell a few degrees does not matter much with this engine sub stage 3 cams in terms of piston to valve, and has nothing to do at all with a lifter failure. The ramp profile and amount of lift has everything to do with it (and the quality of lifter).
