Assuming you have a Quadrajet 4 barrel carb; I'd leave everything on the engine box stock but, give it a sharp tuneup. If needed; rebuild your carb while you're in there.

Exhaust: headers don't do much unless you're going with a bigger cam, 2.02 heads, etc. If it were me, I'd leave the stock exhaust manifolds on there but install a highflow cat and muffler of your choice.
