I will partially agree with it limits your choices on which rocker arms by going with the EZ heads, but as far as performance goes, I think they are the bomb...especially for the price.

I am really impressed with the performance we have acheived with OOTB EZ1 heads so far, and we have not been pushing it. We do not run race gas, we don't launch anywhere near where we could, and we shift it well below the max, and these things run!

I would get a good set of rockers and a set of these heads and be done with it...IMHO. We have run against the guys running -1's and B1's with similar cars that generally run race gas, and we run right with them on pump gas.



I don't have any Indy stuff, and likely never will. But AndyF proves that the EZ's can run. I do have both Victors and B-1's. I have no idea of your setup, but you're doing well to run with guys running B-1's. But that said, they have to be about brain dead or sandbagging if they're not flat out running away from a stock window, pump gas motor. A 500" B-1 engine on race gas or alky will be 800+HP put together by Larry, Moe and Curly. No way will a stock port, stock rocker window get you there NA.

None of which applies to the OP. The EZ's seem to be the best for what he wants. Edelbrock was unwise in not improving the RPM chamber when they did the castings. I believe they're releasing a 75cc head, but I think it's simply smaller, not a better chamber. S/F....Ken M
