I've poked around, and can't find any 12 port head with 45° angled intake ports and evenly-spaced individual ports as shown. All of them had paired ports, like SBC, BBM, etc.
They are paired. "Schultz intake." He made a manifold for individual throttlebodies. KMS throttlebodies, if I looked it up correctly.

These links show some "Howard" heads that have paired ports as you said. One picture in the 1st link shows "Howard" cast into the head. "Howard" is Howard Johansen of Howard Cams fame.
I'll bet Panic is right about the Howard heads having paired intake ports. So What head is shown in the original, non-paired intake, picture?
'57 GMC 102, Original 347 V8, HydraMatic, 3.08 rear gear, added A/C, disk front brakes, HEI, AFB carb, '98 Honda Black Currant paint. T-boned and totaled 10/13 '52 GMC 152 Stake Bed, Original 228, SM420, added A/C, disk front brakes, '67 Chev 3.55 rear gear. Gets used as a real truck.
I'll get ya'll a better picture. Gonna take a minute or two. Got an after lunch meeting, managers roaming through the place, roll up door vendors fixing broken doors, employees that need direction, ..........
The distance between adjacent throttle bodies in your picture is the same all down the head. So each pair of throttle bodies *1+2, etc.) have a "Y" shaped manifold to conform to the 2-2-2 intake ports?
Looks like the nuts are already off the manifold studs. Pull the manifold and look for "Howard" between the #2 and #3 intake ports.
