any pre-1985 13B housing is 12a iron compatible. IE the cooling passages line up. But for amount of work and more importantly, money, i can't see machining a 13b housing down to a 12a housing (either pre or post 85 13B). I would have to verify but i dont believe the cooling passages in the later 13b would line up with 12a irons. Plus you would have to machine a cooling seal groove
