Heads R Us also confirmed that mine will fit, Mine "mic" out to 19.82mm thread diameter.

Penn Diesel quoted me $40 a piece for the injector rebuild (everything included, even the price of the nozzles). As soon as i finish up some other more urgent things, i'll be buying the head and continuing my rebuild. At the moment my Plow Truck needs Brakes, a Hydraulic Pump and an Engine (and with winter breathing down my neck it's high on my list, lol) So once that stuff is out of the way i'll be working on my diesel again.
