Injectors from a 466 are typically 250cc ish "B codes"... While they will bolt right in, there is definitely enough fuel in a B code to ventilate the bottom of the block with a PMR motor.
And before you spend money on a full fuel system, decide what your end power goal is.
Stock fuel system, completely stock system, will support up to a 238cc injector. If you're never planning to go bigger than that, then install a regulated return and be done with it.
Head studs aren't really needed until you get over a 200cc injector either, with proper tuning. Improper tuning, or to much backpressure from a poorly chosen turbo will lift the heads right off with a 238, and can do it with less fuel, depending.
With your truck, I'd probably lean toward some 160cc injectors with a stock nozzle, or maybe a 100% nozzle if you're willing to push the limit a little. My 02 has been going strong for the last 25k or so with 160's in it.
I make the engine work pretty hard too. Try to keep it under 3700 RPM's though.
