2002 5.9 Magnum camshaft

Negative. The can lobes on all flat tappets,have a taper front to back on each lobe.This makes the flat tappet spin.You use a roller lifter on it,it will eat the came lobe up(roller lifter ,harder material than a flat tappet cast iron lobe. You can run a LA flat tappet cam & matching lifters.,in a Magnum(Amc lifters). Also can run a LA hyd roller cam ,as well.
