Procomp rockers???

Problem with cheap rockers is when the roller tip comes off it will cause the keeper to come off and the valve drops into the cylinder and its bye bye engine. Too many failures out there on those cheap rockers and the consequences are grave not worth trying to save a buck there.

Yep, or it breaks in half and 50 little needle bearings go all through the engine in 10 seconds, they will lock an oil pump right up.

Its one thing if something breaks and you can just replace it, totally different when a $200 item breaks and you need a new engine, block even

And it will break, question is just when. Even those $500 arms break but not until they get totally abused in real racing engines
