Why are you stuck on the exhaust lobe side?
Not stuck on it. I feel like I have a good handle on the inlet and how to work that out. It's just the exhaust that I could do with some more feedback on in regards to duration / lift. I know its based off exhaust flow or mass flow but was hoping there was at least some sort of relation to the inlet profile. So if you picked a 6 degree bigger exhaust duration than inlet do you need to make the lift less to keep the inlet / exhaust area the same?
How can you flow an exhaust on a head these days? 20 or 40 years old? The exhaust is in mach speed... The best you can do is help the transition or widen everything because it still has to go down through headers an such. Still thinking after years of 2 stroke exhaust where it does matter....
