Your illustrated intake manifold design probably will not flow air very well, due to the curves, and probably will not flow as well as a stock manifold. Also, the injectors are a long distance from the valves in the head.
Would it be possible to use two straight intake runners, one for each port in the head, and use one fuel injector in each runner ? This might be possible with two injector timing wires going to one injector, and with a diode in each wire for isolation.
Or, use two straight runners, with two fuel injectors in each runner ?
Does the fuel injection electrical system need a crankshaft position sensor ?
Exhaust port matching will not help much, unless the manifold is smaller than the head port.
A very interesting project.

I had thought about having one runner with two injectors, however that adds more complication of fabbing a fuel rail, and I don't feel that one injector per runner would sufficently fuel the engine as it would have to fire twice as often. While a motorcycle engine injector might handle that I'm not sure that would be the correct path to pursue.
While the injectors are further from the head, I don't think that will be a problem if using proper injectors that atonimize the fuel correctly. If it is done correctly there will be no ill effects during combustion.
I realize some of the flow issues with the design of the manifold, but I think that it will have double the flow available coming in that it will offset the curves and merge that it will have.
This first rendition is only theory so far. So It might change based on viable feedback such as your own.
The megasquirt system can actually run of the stock points system from the distributor, though I may choose to go to a crank mag wheel setup.
