While this is true that the iron heads hold a slightly better flow advantage, I was under the impression that any flow advantage they had was negated by weight gain and hotter running temps.
This is true. They flow a tad better....but all that goes out the window too when you start porting them....plus due to holding more heat you can't run as much advance, meaning less HP.
