You know, about 5 years ago, I built a 440 Chrysler and put "chinese" roller rockers on it. I ran the hell out of the engine, but the rockers never failed.

A buddy of mine built a 360 Chrysler for the street and put Crane rockers. 3 rollers went bad and wiped his engine.

For what you want and the price? I would go for it.
