The_aSSet Posted June 16, 2012 Report Share Posted June 16, 2012 Alright here we go. I want a reliable valvetrain in my heads so i was reading up about valvetrain weight and geometry and it seems you want a light valves, rockers, pushrods, and lifters for NA to be able to handle high rpms. im also looking at yella terra ultralightweight roller rockers, are roller rockers worth the money for reliability? If anyone one has any input that would be greatly appreciated. Quote Link to comment Share on other sites More sharing options...
