In the past I've always run the extra short or double-bend headers because I've gotten better top end with them. Should I be looking in another direction?
Not really the crank timing, I got Tesla 5 port GT engine, it share the same crank shaft with 7 and 9 port on road engine. The port timing I guess is different.
