What are stock 360 exhaust manifolds?

Here are pics of the correct Left Side manifold. Sorry they're not great, but I'm still waiting for this part to arrive in the mail! That "Polara" one in the above pic is actually a B/C/E manifold, the right one is correct for A/B/E bodies.

(Left is rear dump, right is center dump).

I think the right side one from the truck will work OK. That's what's in my car now. (74 Dustbag, 360 into a slant-6 K-frame)

Tony, any clearance issues??
