I doubt you'd see a difference. I can see that Fenton's logic may have been, "The middle cylinders 3 & 4 can easily draw off both carbs, whereas the end cylinders 1 & 2 and 5 & 6 draw primarily from only the carb closest to them, so lets bias the spacing to help out the end cylinders a bit more."

Or so it would seem to me.
