I know what you're saying about rocker arm wear but I'm installing roller rockers. Not because I want to but because I can't find stock rockers. In all the research I've done, there's no mention of stock replacement rocker arms available and no mention of a 7.765" pushrod length for the truck V10 engine. I guess I'm just curious if I've got a strange combination or has anyone been through this and found the same issues.
