injector problems

[Sleeper-GSX]

i just got the car back from the shop with a new 1st gen head on the 2nd gen block. the car has been cutting out real bad and i think its the injectors. i stuck a screwdriver up to all the injectors to listen to them and the are tick real loud, its so loud that i can hear them from under the hood when i am driving with my music on. its gotten so bad that my EGT gauge is reading 1600 degrees on the highway in 5th gear at about 65, when before it was at a cool 1300. i tried adding more fuel w/ the afc but then all it does is smell real bad like fuel is leaking out of the injectors.
the only 2 things i know to do are to add some lucas fuel treatment, or have my injectors flow tested. please help me!!!! the car is near its selling point and it has to be running perfect.

Check to make sure the little clips that hold the injectors on(4 paper clip looking things) are there and if so, have the injectors tested.
