Long tube headers are fine for running in the upper rpm band....not something you'll likely see with a 4x4. Short tube headers, will give you more everyday driving power in a useable rpm band. One thing to keep in mind....every vehical has to start from a dead stop, and accelerate. Low end and mid-range are where they spend 99% of their lives, so doing mods to improve those rpm bands will be of the most significance to you. If a mild cam is possible, great, adding short tubed, or stepped headers, with a single 3 inch exhaust will be your best bang for the buck, and add mileage, as well as more power.

To keep you O2 sensor with a dual exhaust system, just have an x, or h pipe as close as you can to the motor and have the shop weld a bung in there, then extaned the wiring for the sensor.
For what to do with the cam and efi, check out what some of the mustang guys are doing, quite a few guys are pumping some serious power out of them efi mills (but i think those guys are running maf though, but if you are up to it find a wrecked stang/lincoln/t-bird with maf and convert everything over).

As was pointed out to me earlier today, some trucks only run one O2 sensor on the right exhaust manifold, and thus true dual exhaust is fine. I find better low end and mid range from a single 3 inch for everyday driving, and prefer it's lower rumble, without the obnoxious rap that duallies give off. Your neighbors will thank you.
