mopar performance rocker shafts?

agree with rusty
BTW get the shaft from Rocker Arm Specialists/ Rebuilders in the Redding nor cal area
Whey they say they are hard chromed they mean grind/ copper/ nickel/ grind/ chrome finish grind the nickel is the key, hard- chrome itself does not have to be thick if the nickel is right
chrome does not stick directly to steel
flash chrome is a fraud- merely a rust proofing and break in aid (on valves too)
and you do not want chrome on needle bearing trunions- you want deep heat treat (not flame or induction hardening- )
so match your shafts with your rockers and if roller tip rockers and of long valves relocate the shafts to get the geometry right
