After 35 years back to where i started need exhaust manifold help

In post #7, the top pic is the same style 318 manifolds as your original pics. The second set in post 7 are B,C,E body small block manifolds. The passenger side will work in an A body, but the drivers side won't. What would work the best are a pair of 72 and up 340/360 exhaust manifolds. Sorry I don't have the numbers.
