If there is no obvious wear at the fulcrum of the rocker to shaft area they're good.

EVERY old Mopar big block I've torn down had some play, in the fulcrum, that was taken out when the oil pressure went up. Not an area of HIGH tolerances held when manufactured as far as I'm concerned. Or maybe it didn't matter when they knew the lifters would compensate.

If you have a replacement PERFORMANCE cam it may have a "smaller base circle" of which is known to cause more valvetrain noise. The fix is longer pushrods or adj. valvetrain.




I have a set of stock ductile iron adjustable rocker arms for a big block. Do I need different rocker shafts or can I use the original hydraulic rocker shafts that were for the stamped steel rocker arms?



I ran mine for while on a set of replacement shafts from Mancini Racing.I would recommend the chromed replacement shafts at the minimum.
