the exhaust will come up big time even with a small straight 4" pipe no bend... even more so with a 12" with a 90* bend

Has Jim sent you the rest of the numbers? That's pretty impressive, from what I've seen it looks like they noticeably better than the CNC version from ProMaxx. What size did the intake runner end up being? That .4 exhaust number is better than most heads at .8.
