I'm not sure, but I believe...

...the Offy manifold with the split runner has only an upper plane and a lower plane.

This intake actually has four levels - two levels in the upper plane and two levels in the lower plane.

The center carb's driver-side venturi takes the low path to four cylinders on the lower plane, and the center carb's passenger side venturi takes the low path on the upper plane. The center carb is on a completely different flow circuit than the end carbs.

I would have liked to take some photos of the intake with the carbs removed, but that was not in the schedule.

Interestingly, I also verified the 352HP and 390HP intake manifolds are of slightly different runner design. I've heard stories and rumors that the 390HP intake flowed 10% better than the 352HP intake, but it wasn't until I compared them side-by-side that I saw notable external casting differences in the runners.
