Best valve shape?
Searched, but didn't find the answer.
My question - Which valve shape flows best in a GSR head? In my experience, a vertical throat generally works best with valves with a pretty flat back and more angled throats work better with 'tulip' shaped valves with a more angled back. By looking at the GSR head, I would guess that a tulip shape would work best, however I would love to get input from someone who has actually tested different shapes. Don't know if it matters, but the head will be boosted.
Thanks in advance for your help.
