Flow bench results for CNC ported Pro comp heads

That’s a pretty nice ET for the flow numbers you gave us. Not great but not bad either. I’m not sure how did your heads but is there any chance you had a valve job done? If it’s who I’m thinking of I’m pretty sure this guy used let’s say non standard valve angles. And if a more normal valve job was cut and already big throat may be bigger yet with your 2.055 valve. Just thinking outside the box here.
I will post some pictures of the head chambers and valves later.
