I don't know of anyone with stock heads/cams that needs or has performance rollers.I believe they are to improve vavle timing on such applications. I think you would only really benifit or need these if your vale lift has been increased. I'm not 100% sure though....


I do knwo they reduce friction which inturn reduces oil temps and that they also increase rpms... at least thats what I have read.

I believe those are not for OHC engines... They're for pushrod type motors.

Those rocker arms are for pushrod motors. Not overhead cam motors. But they help with providing more lift if you get a higher ratio. Like from the stock 1.6 to 1.7. But by doing that it puts stress on the pushrods. Also it has a roler tip on the rocker arm and it takes friction out of the valve train freeing up horsepower. Also where the rocker pivots on the pedistal has a bearing which helps lose friction.
