Let me ask this then: is there a head you can you run out of the box, that would not bennefit greatly from port work? Or, which comes the closest? If I read this right....AFR and Edelbrock would qualify according to xntrik. Which do show lower CFM and if I remember around 75% on exhaust/intake ratio's. But maybe they have a great chamber design and strong velocity? I'll take a look at their mid lift flows again...something I have not really compared much of yet. BTW, thanks to everyone who has posted. I'm learning more from this exercise than probably any other thread I have started.
