Another lifter noise question

the shafts are on right ,slots down.I will check how much wiggle room there is.I thought only the 273 rockers had clearance problems not the stamped rocker.I'm going to take a look at that.If all checks out I think I'm going to pull the motor and tear it apart.I keep thinking about if the cam bearing holes aren't aligned well enough,although I saw no signs of galling on the rocker shafts.Because my thought is it quiets down at higher rpms,more oil being forced up there.I took the shafts off and cranked it over and oil only came of 2 of the pedastals,one on each side.The amount of oil wasn't much.
