Got me a new truck with a slant Six, what should I do?

I'm posting here first because you guys have the most knowledge about these motors over the truck forums I have seen. So on to it.... I recently purchased an 81 Dodge D150 short bed utiline with a 225 4-speed. The motor is bone stock with a single barrel carb. So my question is what should I do as far as engine performance mods? I was thinking a dual single carb set up with headers and possibly a cam. I plan on driving the truck every day so nothing too crazy:toothy8:
