“Wiped Cam Reveal”

In the mid 2000’s I lost several cams, and it was the chinese junk *** lifters.

To this day a lifter doesn’t go into an engine I do without checking every single lifter to make sure it has the correct radius on the bottom.

Since doing that and weeding out the bad lifters I haven’t lost another cam.

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.
