I had the same problem with my 65 C10. One would clatter. It would go away when properly lashed, but would loosen up. It was solved by a new rocker arm nut, a freebie from my local machine shop. Installed, lashed, two years of no clatter. I've read that you can re-squish them into an oval with a vise, but they are cheap, so why bother? However... seeing that you tried swapping over the rocker and the nut, I'm at a loss.
