If your not concerned with the stock looks (Since you put efi on it im guessing your not) I would go with a set of high quality ceramic coated headers. When I rebuilt my motor I did some port matching, though I wouldnt do it unless your pulling the whole motor. If you dont mind replacing all the gaskets you might as well pull the motor, then you can clean up the motor and engine bay too. Im pretty horrible about having my projects snowball on me though!
