They are just a P-style nozzle, which are all dimensionally equivalent within the same family ie; sac type or VCO, the later Duramax has a 7mm shank. Depending on what year Duramax the nozzle came from they can be 6/7/8-hole, impinged or single plane, the cone angle ranges 158-159°
If your area of interest is if you can run a common rail nozzle from another application, then yes as long as the needle guide diameter and style is correct to match the holder.
