Replace rocker shafts for sure

rockers hitting the retainers usually means the shafts are too low
whats with those rockers?
aluinim on steel?
needle bearings
wtf
rockers may have to be bushed
contact rocker arm specilists in anderson ca
unless your rocker and or shaft vendor supplied incompatible parts
but I'd do the stripe width test fitst and then the centered on the valve stem test

sorry about this mini
needle bearing rockers need case hardebed- heat treated shafts
not stock or flash chrome
