Whatever happened to whitepunkonitro

Im not confusing anything. His claim is they they were manufactured without a crown, and as I recall, could be wrong, he shows machining marks on the bottom. How is that his fault?

You could be right, but you present ZERO evidence, so it's only your opinion.
It's hard to prove they were made without a crown after you run them on a cam and damage the surface. Now, if he had a NEW never installed lifter with no crown, I would agree that's a problem. (And it does happen) but its irrelevant after you damage them.
