The pics I posted are of the RPM style heads. These are what is being talked about as being easy to get to 300cfm. This is the head that’s the same as the Sidewinder head.
SM, Sidewinder, Stealth, ProMaxx, E Street........ those are all direct competitors.
The Victor style heads flow over 300 ootb, and frankly....... in my mind aren’t really part of the conversation when one is looking for “budget” heads.
