Agree with all your points Ross but one sticks out to me. Sticky lifter bores. Having done long ago a number of in-car cam swaps, we noticed that the removed lifters had deposits on the lower (cam side) ends. Taking out the lifters showed similar crud inside the bores, hard to remove even with determined cleaning. We noted that some of the new lifters had trouble spinning in the bores. We went back in with lacquer thinner, acetone and even gasoline until the lifters spun easily.
Yes, if they can't spin, the lobes will go flat in a hurry.
