I've been thinking of upgrading my old cast rocker arms and shafts to stamped steel while I have the 6.2 apart. Is this something I can get away with running used parts, or would I be better off saving the money for new? Rock Auto sells Sealed Power shafts for 30 a piece and Melling arms for 10. Whatever I end up doing, I'm planning on getting a brand new set of buttons for them. If I were to go with a used set is there anything I should be looking out for in terms of wear/damage?
As always, thanks in advance for any advice!
