Buying a rebuilt set or even a new set will not guarantee 5 bar balancing. The specs allow a 10 bar spread even on new.

I would add that once rebuilt, injectors should be tested and adjusted accordingly at about 6000-8000 miles. At least that was the case with mine. The new nozzles "settled in" and consequently got slightly out of calibration (since we're shooting for perfection here) - my father remarked that "a diesel either runs perfect or like sh*%," "there is no in-between" - these words have haunted me for some months now.
Also, my FSM calls out 5 bar not 10, and Rod at Diesel Fuel Injection Service in Portland knows I like them within 25 PSI of each other - and he can do it.
