Yeah I would still check the injectors just because I bought three different sets from three different sources and all of them were a mess when I bench tested them. I've never seen anything like that with Bosch or Rochester any other type of injector for that matter.
Now I suspect any Toyota injector (and I'm not a big fan of the rest of their FI system either as you may have noticed). My 2FE is a complete redo of the fuel delivery and a aftermarket ECU with a crank triggered ignition. I kept the Toyota injectors, but only because I had plenty and milling the hardware to use a Bosch was too much of a pain.
