well someone needs to tell the racers in NMRA Pure Street that their heads are not flowing over 6000rpm, since most leave the line at 6000rpm, and shift with a carb on the northside of 7500rpm. I think John McGowan would say differently about that statement.

I am not trying to flame or start an arguement, but Edelbrock says a safe limit with their Victor heads is 8500 rpm, a Hot Street cars see's no less than 9000rpm on the shift unless they are running a serious torque application.

You have to becareful with what head manufactures say in their claim, they also are trying to protect themselves and their product.
