AFR Heads
What does it matter what the casting was, point was application.
But I've yet to see you compare it to other fully ported heads. That's the point.
So far TF 190 is the best flowing head I've heard you compare it to, and obviously TF aren't sold as a low 10 - 9's second head, so I wouldn't say there in the same bracket.
I am comparing to any of this family of Edelbrock copy head. They are all basically the same head. You can buy the “ shocker” cnc ported head, a company called Toth takes these heads and cnc ports them and sells them( or did) Hughes offers a fully ported stage 3 Edelbrock head, they even offer a “ big mouth” Eddie head that has the pushrod moved over, etc, etc, there are others too.
You do know that the Bloomers are just CNC ported as well, right.
They are CNC’ed at Bischoff’s( BES) get the valve job done there, then Rod assembles them with your spring choice. Same basic thing all these other CNC heads have done, including trick flows.
They are CNC ported, then trick flow sets up the springs per your choice, roller, flat tappet, hydraulic, etc.
Regards the AFR heads, they are just an Eddie knockoff like all these others, and from what I understand, have not been CNC ported.
Maybe where the misunderstanding is, only some of these heads have been CNC ported, and offered that way. I listed a number of them above
