You couldn't use a ductile iron rocker on a stock stamp steel rocker arm shaft, they would gall up and ruined the rockers after a while, been there done that


I had two motors, one with Iskys and the other with Cranes. Both with stock shafts and tons of street miles with ZERO problems. Pretty sure only the hemi rockers were bushed.

Anyway, its a moot point since we're all advising a decent aftermarket shaft. My main point was that hard chrome is not a necessity in this case.
