Yella Terra is what I prefer, lighter weight over the nose and the best swipe patter across the tip of the valve, plus it is a shaft mount style rocker which utilizes the best strength. The problem is supply can not meet demand with it, quite often on backorder...

Factory is 1.7
Just remember with (L76,L98,L92,LS3) the exhaust rockers are conventional (straight) and the inlet rockers are offset.
