“Wiped Cam Reveal”

How do you check if the radius is correct? I at least swap mine around the lifter bores if they seem to fit a bit tight in the first one. I've only put together 2 Mopar engines so far (both in the past decade) with flat tappet cams but didn't have one go flat in either.


I put them in a lathe and run a dial indicator across the face of the lifter.

If you don’t have a lathe, you can do as gregcon said. At least you can see if they have some radius to them.
