How about drilling the manifold runners on the horizontal plane so the
injectors squirt straight into the port. The holes would be tangential to
the curve of the runner.
You need to fire them FFRRFFRRFFRR. for 1342 firing order
OR
put 2 injectors in the top, and two in the bottom with 2 rails. Put them in
about 15 degrees off horizontal each way
