The manifold flange is ready for porting to match the head on this the engine side.

Here is the set of throttle bodies atop the short runners. The fit will be better by shortening the runners to between 1/2 and 3/4 inches. They are at the design height of 1 inch now. 1/2 inch should be sufficiently long to grip the rubber hose that I will use two connect the two assemblies. I will also gain clearance at the radiator by keeping the runner short. A side gain will be an increase in turbulence at idle by having the throttle plates close to the head.
Thick walled ABS black pipe will allow good port matching to the throttle bodies.
