So I've noticed, I dont see ppl talkin about aftermarket main caps or rocker arms. Are the factory main caps comparable in strength to the factory crank? Meaning unless your makin unreal power you dont need to replace em? As for rockers, same thing. The only set I can find is the Ferrea set, but their description says they "cancel" vtec. Does anyone make a set of billet rockers that allow vtec? Im just lookin to lighten up the valve train a bit for some more high rpm stability. Thanks in advance for any info.
