Heads are on!!!

Ok last nite(actually 2 am this morning) i drove my car home. Thank you for everyones advice/help. finally after a year of the heads sitting under my bed are on! The car pulls harder now than when it did on nitrous with stock crap. and the idle is soooooo sick. it sounds like i have a cam with like 600 lift :nice: set up is-
-proted iron windsor gt40's
-non egr 5.0 explorer upper
-a/c delete
-air pump delete
-155 lph fuel pump
-holley 110 nitrous
-full exhaust, cold air, msd ignition, etc..

i currently have the stock tb, mass air, injectors, and cam.

what i would like to do is leave my stock mass air and injectors(to save money) and get bigger ones with my supercharger in a few months. but i am not sure if the stock injectors and the pump i have can support the nitrous now???? keep in mind it is a wet system
