Re-using Used Lifters on Another Cam

I will add that my pops opened his auto shop in '79. When he started to work on other brands other than mopar he did encounter cams going flat. Especially the old straight 6 ford from the late 70' to 80's and also several 350's and quite a few 454 chevy big blocks. Then he started to break in cams because of these failures. He also talked about 390 fords were also bad with cams. So he always was a mopar believer since he never saw a mopar cam go bad!
