Speedmaster, Edelbrock, ProMax head question for you guys

The only thing different is the valve so the more I think about it because I’m limited in what I do to the chamber. I don’t want to lose the customers compression and trying to keep my pricing down for the average customer when I get time I’m going to play with the top angle and the backcut on the valve. One or the other would let me tune the head to the customer more for those choosing to run the Liberty valves. For most guys the low lift numbers will play well with their combos. But for those wanting higher lift numbers and cheaper valve options the answer is out there. I’m just running out of time and energy to test like I’d like to. Most guys that still port heads and do machine work quite racing years ago. I’m not going down that road.
