Fuel injection for the slant six

I sure wish I had your talent with just building stuff out of the blue like that. I'm just a clusterf#$k. One question though, and I seem to remember you said why elsewhere, but why did you put the injector in the head instead of the intake? Closer to the chamber?
Very Impressive! i would be curious of performance. being the difference with injectors in the head.
assume easy start? etc..
