This head was designed for midget racing (4cyl).

It shares alot with the non hemi head p5 this is just light weight casting.

Yes they are injector bosses in top of intake runner.

No cast intake for this head like to see how p7 lines up or maybe big LS C5R intake.

The other big down side is set of castings will set you back about 5k

Right now in take is at 3" right now I am gong to try to get 4" cross section.
