Instructions are to stay high as you can installing injectors so you can get as much oil burn as possible and maybe less oil on your belly. I have seen installations where the injectors are maybe 6 or 8 inches from the end of the exhaust pipes. I stayed as close to engine as I could. You drill 1/4 inch hole, unscrew the injector from the flared fitting, push it into hole, align the flats up and down to make injector spray horizontally, then tighten down the heavy duty wide clamp, and screw on the outer flared fitting. I don't know what to use to seal those threads, but it probably should be something nickel. Its going to be hot there. We'll see. I will ask Marvin. He knows everything about this system. He designed it.
