Chuck, I think your 100% correct, before Appliance headers changed to Blackjack the CH4 number was used, pretty sure the blackjack number is 3017, same header later issue.

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.
