And I agree that if all those poly locks are all the same type and are tight in that last picture, something is wrong. The inner lock portion should be pretty consistent across all the poly locks. The Crower rockers have a little recessed area in the trunnion on one side for the poly lock.. Maybe a couple of the trunnions are flipped upside down?

different rocker arms can sometimes require different pushrods. It this was my motor, I would pull the intake and Valley Pan, and verify the condition of the lifters, cam, preload and geometry.

It would be a good idea to check those trunions and make sure some aren't upside down. That would account for the inconsistent set screw height, possibly some noise.
