Not Ranked
I have had my Sig Erson roller rocker arms for 8 years (I originally bought for my 428 CJ but I have since switched them over to my 427) and I have never had a problem with my top end. Like you, I originally had the stock type rocker arms and after breaking a couple of ends at very in opportune times I sprung for the more durable Sig Erson rocker arm assemblies. Not one complaint and I thrash my Cobra around the track quite a bit plus ample amount of street time. T&D and Harland Sharpe are also very good brands.
