Re: Which Headers
In an exhaust system designed to scavenge, the pulses travel along the tube right against the pipe wall, not down the middle area. It is a pulse, not actual gas flow.
A 1/8 reversion step is definitely worth the effort on a flathead race engine with "W" headers.
There was a book written by a guy named Ricardo many years ago explained the whole thing so any rocket scientist could understand it.
