Someone ported the HPs before Barton got them. He could not fix everything but did the best he could with what he was given. True ??
Barton is the one who told me a good set of High Ports would run away from CV-1s. The guy does top Pro Stock stuff so its not like he does not have credentials, he does.
Slick insinuated that they were ported since he said they came from a successful team. But I do remember the Pickets running as cast HPs for a bit.
As cast, that makes sense.
And no, I personally don't like CVs. If you are going to cant the valve you should rip the head off every inline Pontiac head there is. Something was not right, those things were supposed to be one head that could do it all. But like many things you can not try to be good at every aspect or you end up master of none.
I take much joy when they can not beat a aluminum PMD RAIV type head.
I am after all, a Pontiac fan.

There is no rest of the story. Yes, they were mildly ported before Dan got them, flowed around 355 cfm. But, he did a great job taking care of any and all issues they had. He originally got 388 cfm out of them. I sent them back to him a couple of years later to freshen up. He did a few other things to them, but I didn't have him re-flow them. 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...

One last thing.... my car ran 8.80's before I pulled the heads and sent them to Dan. First time down the track after I got them back from him I went 8.60's. Then, 2 years of tweaking and tuning and him freshening them, I got it down to 8.38. So yes, he got all there was to get out of them.

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