He said they should flow a little better, though. As I said, he did a great job with them, probably in the 390+ cfm range after freshening them. I don't think anybody's gotten much anymore then that out of a set of standard port HP's. He also ported my BOP intake to match them. Dan's a good guy and for sure knows what he's doing. I have nothing but good things to say about what he did for me and my HP's. But, like the rest of us, he's human and he was wrong IF he told you a good set of HP's, at least standard port HP's, would run away from CV-1's. That wasn't the case with me. Like I said, LET IT GO, I'm done with this...

And now, these heads/intake reside on my 535.
