We PMed each other several months ago and on his rebuilds; besides Pop Testing he also laps those precision surfaces.
He also has an Ultrasonic Cleaning Tank.

Yes, yes and thank you. I've been busy the past few weeks. NO manufacturer, I've ever heard of, makes nozzles (to be installed in injector bodies) that DO NOT need to be tested - did that make sense? All new nozzles installed should be pop tested when installed, regardless of make. Monark's NEW, ready to install complete injectors are set from the factory. I check them at random (about half) and none have ever been off. As for the servicing - I stick to MB's FSM, "Dress the surfaces {see red arrows in photo above} before reassembly." FWIW, this also applies to VW, Volvo and a fork lift I once worked on. For the benefit of any new folks, when we say, "lap" or "dress" we DO NOT mean removing measurable amounts of metal, leaving any
new machining/sanding marks or rounding the edges in
any way. Your objective should be leaving a shiny, clean mirror finish. Also, when we say, "clean" the injector parts we mean thoroughly, completely and as much like a NASA satellite assembly room as you can possibly get. It is not unreasonable to spend up to 30 minutes on
ONE dirty injector.
