Best Cylinder Head Porting Shop/Vendor- Your Experiences w/Results

oldmanmopar makes it sound like the cnc fairy comes down and sets up the machine to do a perfect port job every time. Lol. Wake up man. Some of the cnc’d Heads I’ve had on my flowbench suck big time. One of my Chevy friends brought a set of cnc’d AFR 220 heads over for me to flow check and he was so pissed he wanted to throw them through the guys shop window. He asked me if I could fix them and I said ya I could. I have never seen a cnc’d head yet that couldn’t be improved and I’m not talking by a few cfm either. Like someone said above. Junk in, junk out
