OK my question is, I just got a compleat valve job done, new timing belt, water pump, 2 new fuel injectors, etc. My question is. should there be a big difference from the way the rig ran then and now??

I would think your mileage could get a little better, and your engine will last a lot longer than it would have if you hadn't done the work done.
Bad injectors could ruin a catalytic converter if they were dumping too much fuel, and cause carbon buildup, etc. Mainly it sounds like you had general maintenance done, not power mods.
