It does answer the question though, that it appears there are at least two versions of the manifold.
The only thing I would tell everyone is that particular small port is the only one I've ever seen.
Didn't Kelly Coefield in a previous post, say that in addition to the A331-A3 intake, he had one that fit the as cast B302 heads (like George's small port) plus one that fit the B351 heads but wasn't sure if that one (for the B351 heads) if that was just a small port opened up to match the B351's? Kelly?
Should we just call those A331-A3, A331-B351, A331-C302?
As I remember, that small port was about 6 or 7 pounds heavier as well because the runners were closed down so much?
As I said previously, the problem with the A3's is finding one of those manifolds to use.
A STOCK Torker closed down to match the head ports, is a very good alternative for them now.
You can use the tall spider manifold but it is not likely to fit under the hood.
I don't think either one of those "Torker" manifolds was listed in the Motorsport catalog back then either.
The ORIGINAL C302 heads used the standard Boss 302 7/16 rocker arms and studs, not the shaft mounted rockers.
Here's a complete set up for sale somewhere in the past,

They show studs, not shafts.
I think these are getting confused with the Yates heads? Those use the shafts instead of studs.
IF you were interested in this set of heads, you want to see what the intake ports look like.
Why the seller didn't post pictures of those, I don't know.
Things like this/that tend to show the misunderstanding of even what the owners of the parts know about the parts. I'm afraid that the Chevy people have seriously infiltrated our ranks for the purpose of just creating confusion amongst the most vulnerable of the Ford newbies?
