The manifold in the pictures is a standard off-the-shelf example of the Edelbrock Torker version of the A331 manifold, its not a narrow port anything, its not the manifold I acquired from Doug.
Everything I previously typed somehow got deleted.
Here's a picture of the A3 intake next to the A3 heads that the guy in Texas had for sale on ebay last week. It makes me wonder if there were two version of the Edelbrock A331 casting in addition to the Roush A331 casting. These ports look quite a bit different than yours. They look more like this one:

I obviously have a lot to learn about these old school speed parts. Until a month ago, I didn't even know these aluminum heads existed. I still want to learn more about the B3s, which seem to be even less common. C3s aren't an option for me because they lose the Cleveland valve cant and require an expensive shaft mount rocker setup. I don't plan to ever pull the revs to justify such an expenditure.
Very cool stuff. I'm glad I joined this forum.
