beefing up the stock 318 engine CHEAP mods

I have a bone stock 318 in my 74 dodge dart that I want to beef up a bit. I will admit right now im a cheap ass and dont want to sink a fortune in this thing. With that being said, what can I do for cheap/free? It already has dual exhaust with no cat. are headers worth it? dont know if its 2bbl or 4bbl, but maybe bigger carb (is the 2 to 4bbl upgrade cheap?) what about removing the smog pump and a/c? ar advance the ignition timing? bypass fan clutch? Im new to mopars so forgive the newb questions
