Nexxussian:

I'm not sure how the Falconer L6 (24) ports are done. From looking at the photo, it appears the 6 injectors are an extended oval shape that suggests each of the pairs of intake ports merge (dare I say, siamese?) before they exit the head. As I recall, that was typical of many 4-valve DOHC heads including the Offy's.

Of course I could be wrong - wouldn't be the first time and certainly won't be the last . . .
