Those are not roller rockers. Those are roller TIP rockers. You don't get as much of a performance gain from them (if anything).
Just my opinion but if you don't have the money for roller rockers by Crane, Comp, Harland Sharp, or one of the other name brands I'd stick with the stamped steel stockers. Cheap roller rockers are notorious for failing (C.A.T, Scorpion).
