Thanks guys. These are flow testing heads. Trying to find the best performance out of a 2.02 valve. Factory throat on one head is 90.5%. Factory throat on a factory CNC head is 93%. I want to try a smaller throat before I try a larger valve.
Unless you close up the bowls, use a larger valve or a steeper seat you‘ll be in trouble. Those bowls are too big for that valve. I’m not sure why they do it, but they do.
