I will call Ray Monday and see if I can get the info on the heads. I will say that I really can’t see how you could get any more flow out of these heads other than going bigger on the valves they are opened up all the way into the pushrod passage and he installed bronze tubes in them to seal the ports up. The superformance intake gaskets I got have to be opened up quite a bit to match the ports. When you start talking flow numbers how does one state definitively that the numbers are true? What one head flows on one bench could be more or less on another.
Oh and I replied to your post over on FBBO about my experience with Ray. He done my heads and spec’d
my cam and picked the lifters the carbs and intake.
I measured and ordered my pushrods from Smith bros.
