Early A exhaust manifold questions

I shot from the hip on the 65 Valiant 273-4 information and sorry for it being incomplete . The discussion did bring out the production figures though. The Galen book includes total 273 production and no breakdown for the 2 and 4 barrel engines. There is plenty of information from Ulf posted by @65 Dartman in post 41 (thanks) and sales information from the Hamtramck site to prove the HP 273 was available in all Valiant models except for the wagons and Barracuda models.
