'pro comp' roller rockers

It's hard to evaluate parts that have a dubious reputation . I look to the racing community to see which parts that stand up to the pressures of competition . Our small block uses Harland Sharp roller rockers . Our bb uses Crane . No issues so far . It is my understanding that Comp rollers are an excellent product as well . We have used factory rockers into the 12 second zone but that's like having a grenade in your hand with the pin pulled . imho
