one of my poly lock nuts is sitting noticeably lower on the stud than the rest of them. I was thinking the cam lobe but both lifters for that cylinder are sitting equally in the bore when they are on the base circle. Thought maybe it was a bad lifter but after swapping another one it is still the same. I readjusted the lash but it made no difference.

Yes they are all the same height but I think. the problem was that both lifters I tried were bad (bleeding down) issue cost me a new set of lower intake gaskets. Just as well maybe time for new set of lifters.
