Horsepower limit for out of the box Edelbrock RPM heads
There are pics posted on the Jegs/eBay listing for the ProMaxx shocker 185’s....... the floor of the intake port, as it gets close to the short turn is untouched(no cnc marks).
I don’t see how there could be a lot of short turn profiling in that situation.
That’s not to say they still couldn’t flow what they claim.
As for the exhaust port........ I’d gladly give up a few cfm to retain a little more flange thickness/width to help with header gasket sealing.
