I see the TF heads have small exhaust valves has anyone thought about putting in bigger valves to help with flow
Why do that when you can increase the exhaust duration, if needed When the exhaust valve opens it has a bunch of cylinder pressure waiting to escape, open it sooner to let it out longer if needed The B1 and B1 MC heads(2.40 intake) both have 1.75 exhaust valves is what I'm remembering
