It depends on what you want to do. Best flow numbers rarely mean best performance.

If you want a lower RPM range streetable car, a dual plane is usually the way to go (though you can run some smaller single planes)

If you want all out flow for a high winding drag motor, a single plane will outflow any dual plane.

What are you building?

Oh... just reread your post.

As far as stock is concerned, theres nothing too fantastic about any of them.

The stockers are pretty much all the same to my recollection, though I think shelby and ford motorsport made aluminum versions.

Some windsor engines in the early 70's had police heads with 1.94 /1.54 valves, and they also had a better stock manifold too. Most top of the line heads had only 1.86 1.46 valves...
( if I remember correctly)

They didn't. 1.94 is a Chevy valve.
