This is a 350 Tune Port Injected Chevy I wanted some ideas on the best
way to gain HP the cheapest ways?? My first thought was the cam and
some work to the heads.The complete overhaul kits was in Summit for
like $180.I can do the work if I switch the intake to Carburetor that will
take care of the wiring and vacuum.I'm a new be at this!!!!

You are going the wrong way, you can gain a fair amount by changing injectors and getting a reprogrammer for the on board computer system, then you can add in a cat back exhaust, fresh air intake system, if you want to get serous about horsepower gains you can change to higher compression Pistons, larger valves or different heads completely.

I agree with tennishoes completely!! Try the reprogramer route first....
