A TBSS or NNBS intake manifold along with the bigger throttle body would be a good setup. Its a pretty straight forward swap and can be done pretty cheap. The main expense will be the throttle body. You'll need to adapt a drive by cable setup to fit it or swap it over to drive by wire, which unfortunately is somewhat pricey. The style heads you have now are pretty good at making torque. Injectors aren't really needed until you are maxing them out, which a very mild setup like you are talking about isn't going to be maxing them out. If you go with a small cam then maybe you might need them. I've seen plenty of guys running stock injectors with a small cam without a problem. Could the injectors help? Maybe. You'll need a good tuner either way and he will be able to let you know if you're running out of fuel and need to go bigger. A good all around setup for these trucks is the intake manifold and throttle body I mentioned, cold air intake, (air raid jr. and a good drop in filter is all you really need) long tubes, a good tune and Efans. Throw in a nice baby cam like the one mentioned in a previous post or another low lift type cam and you'll be surprised what a difference that setup makes. You'll make great usable power and still be reliable as hell. Very daily driver friendly.
