The short answer is yes. There were different configurations that were on some years of big cars and F-body. But the basic rear dump log manifolds are functionally the same across years and engine sizes. The manifolds on a tri-power GTO are exactly the same as the ones on the same year 326. They could also be swapped on to a 350 or 400 or 455 in an A-body up through the late '70s.

My confusion was I saw on the Wallace Racing the same casting number manifolds used on motors that were supposed to have 2"headpipes while others had 2 1/4". Were the 2 1/4" necked down to fit. This info has departed my brain thru the years and you just can't go out and order them anymore.

The PY Online Forums is the largest online gathering of Pontiac enthusiasts anywhere in the world. Founded in 1991, it was also the first online forum for people to gather and talk about their Pontiacs. Since then, it has become the mecca of Pontiac technical data and knowledge that no other place can surpass.
