Another stupid question that has popped into my head. Is there a difference in runtimes between the 3, 5 and 7 ports? I'm just trying to decide between a Massive Mods 3R, or a stock 5 port.

I Had 1 Go engine dynoed that I modified, it was a 5 port .25..... I gained well over 1 HP onthe X-Dyno at several points in the powerband, mainly a giant gain at around 28000 RPM and up......definitely these GO respond well to port cutting.......after I was done the motor was a ripping banshee !!!! Also getting killer results from the 7 port, a few adjustments to the blowdown timing and the motors bottom end comes alive with no loss of top end...I Have yet to play much with the 5 port, as I prefer the larger exhaust of the 7 port....
