Can I put AD injectors in my 94 powerstroke?

AD injectors

You can, but why would you want to?
AD's are split shots. Stock OBS Powerstrokes (such as your 94) have AA single shot injectors. Right off the bat, you'll need tuning to run split shots, as single shots use different (and significantly less) fuel pulsewidth, as well as injection delay timing.
Next, since AD's are split shots, they use a considerably higher volume of oil to fire. The Superduties that used AD injectors came with a 17 degree HPOP. Older Powerstrokes used a 15 degree HPOP, which has a somewhat lower oil volume per revolution. So you're stock HPOP will struggle to maintain oil pressure at the injector rails, especially under load (such as towing), or WOT.
Basically, yes you can do the swap, but you'll need to address tuning. In addition, if you don't address the HPOP, you're going to lose oil pressure to the injectors, and thus lose power and add smoke.
