Dozens of Horror Stories on the forums.

If the lifters do not rotate, the cams go flat in a real big hurry!

But then again, John, if the lifters don't rotate, most likely the cam was ground incorrectly, probably not enough (or too much) taper on the lobe.
Luckily Mopars have a larger diameter lifter, that's a plus.
