Erson rockers

I've yet to break a Crane Gold Race rocker. They are not roller fulcrum though as I don't think you need it. Those were developed for Chevies because they had to restrict the amount of oil going to the rockers because the valve covers would fill up at high RPM's. Not enough drain back.

Although I will admit they look very nice. Especially compared to my battle scarred Cranes. :^)
