I put a lot of those Appliance headers on in the early 70,s when I worked at a local Calgary speedshop JB,s Automotive , very nice headers very equal length too. I have a set of CH3 headers for a small block Camaro been saving them for years. FWIW when Blackjack took over they changed to that rotating lower flange.
