I've hit on this in a few other threads but just to reiterate, anytime you run an aftermarket heavier rocker set-up, you must opt for our 8019 spring upgrade. It handles the heavier valve gear much better at RPM due to the additional seat pressure and spring rate. Also, at that point in time an aftermarket lifter (Comp, Crane, Morrel) is not a bad idea either.

Damn..and we thought these Crane Quick Lift rockers were the **** and they weigh half as much as my Comp Pro Magnum..just thought we'd try something new...live and learn.
Stock rockers arent going back on....he's not going to take a chance...they are junk anyhow in my opinion...sounds like he should have had the spring upgrade I guess.
He might take you up on the Kooks offer though.
