“Wiped Cam Reveal”

A couple posters mentioned Mopar Performance cams and lifters. I have an old nasty *** MP box with the nos mechanical cam/lifter kit from what I believe is at the earliest 1991 (box iirc shows 1988, various paperwork has 1991 with the copyright info) Who would most likely have ground the cam, but of more interest is where the lifters are from?
