i read that with heavy spring rates and high lift cams, that the stock stamped steel rockers can crack and bend? and also the push rods too. i am using a mopar performance cam with over .400 lift. and mopar 5.9 springs, keepers, retainers. Any info?
thanks guys, bryan

Re: rockers
I run the mopar 30ab cam(.045" lift) w/ the 5249464 springs and associated retainers and keepers. I bought sealed power factory replacement rockers and their 9.602" pushrods. I'm at 10K now and all seems fine. I will check out the valvetrain when I replace the cork gasket with a rubber one.

Re: rockers
I'm running same cam/spring combo, except i'm using yella terra 1.7 roller rockers. I've only got 2K on the engine so far, and all is good up to this point
