You can pretty much do that for the intake side of things as well but we will leave that for another thread because this is going to be complicated enough. So what's wrong with the port I ask? Countless engine builds putting up big numbers N/A and Boosted. I really want to know what's wrong with it.

I've used both Darts(355 cnc) and AFR's(357's),made ~1200hp(touch more) w/ both and the cams were very similar.The 4L whipples were getting close to my safe(I don't like to run over 9psi) limit.

I think black baja was referring to what "Ben Perfected" stated in the other thread. What I got from the thread a couple years ago where JimV was posting, was that when he flowed several sets of AFR heads they did not flow the numbers claimed on AFRs website , on his flow bench. I think?

I believe he said it can be improved. Just like the Dart intake port, his opinion. I don't believe something is wrong with the port.
