The '56 2bbl intake would likely be the most improved of the older 3 bolt versions.
The '57+ intake manifolds with a 4 bolt carburetor flange were built with improved runners and have better air flow characteristics... for the slightly higher horsepower engines available then.
Fyi, the '56 and older carburetors are vacuum matched to less desirable Loadomatic distributors for their ignition timing. They aren't the best option.
