1967 big block A.I.R. exhaust manifold

[Louis F.]

Are the exhaust manifolds for an Air Injection Reactor 1967 big block the same part # (827/828) as a non A.I.R. car. I looked in the judging manual and there is no mention of it.It only states the 827/828 is for a 1967 big block.Thanks ,for any help.

Manifolds casting #'s are the same. Just the machining is different
