Like you said, carb and intake (obviously). You will also need a non-TFI dizzy and a carb-rated fuel pump (MUCH lower pressure than EFI pumps). Carbs don't have a return line, so you can get rid of the EFI return line and plug that hole in your tank. Thats all I can think of right now, if I can think of anything else I will chime in if no one else beats me to it.
