Jeff, hey there big guy, Really the only thing I was referring to/pointing out was the V area that feeds both outbord runners calculates to only ~14% larger than the sum of the 2 runners nominal Max Wedge cross section...in other words, all the air that passes to both of those runners/ports HAS TO pass through (or...is LIMITED TO) that V area in order to get there..., isn't that correct? compared to an old Torker/TM7 (for example) where all the runners lead directly to the ENTIRE plenum, it must be a completely different flow theory. That's the only thing I was pointing out, that's what I'm trying to get my head around....nothing about the runners themselves.

I agree that the flange mating surface is just that...the true intake 'runner' is the entire length from the valve to the plenum.
