Speedmaster, Edelbrock, ProMax head question for you guys

I’ve always heard people say build the engine around the heads. In this case building the engine around the valves, is a possibility. A lot of people don’t have a chance to see a comparison like that. To test different valves to suit your needs. Both set of flow numbers would be appealing to most people building an engine. But to see them side by side, with just a valve change is very interesting. Thanks for sharing. Personally, I’d go with the liberty valves with a lower lift and a little more duration. Less spring pressure required and less strain or resistance on the cam shaft. Just my thoughts
