The lower nuts holding the bungs had to be ground down to 3/4" diameter to fit through the holes with the bungs. I ground flats on them so I could tighten them with a wrench. The bungs ended up withing a few thousandths of each other in height. I pushed them as low as I thought I could get away with so the injectors will be as close to the port wall as possible.
