Help with 1966 fury sport

Hey guys I recently bought a 1966 fury sport with a 383 commando v8 in it. I was just wondering what kind of headers would fit on it and what's the best set up. I was thinking of doing headers then adding glass packs with some down turn tips and was just wondering the best way to go and what size I could use would like to have at minimum 2 inch piping preferably 3 inch if it would work.
