alright sounds good, i havent found anything about a valve to bleed air either but ill take a close look at the back of the heads tomorrow(still been working on that toyota after work). today i turned the 7.3 over and it fired up and idled good for the first time, i let it idle for about 20sec then revved it up some and drove away, made it to the end of the driveway(about 75 yards) and it lost power and stumbled then died and wouldnt start again, let it sit while i worked on toyota and then turned it over again and it fired up but only for 2 seconds again. So.. looking more like air is what im thinking

really wish i could just bleed it at injectors.
