Engine Serial Number Decode and Crankcase Ventilation

The number on the tag is 3230S

1962 170/automatic, non-taxi, non-fleet, without PCV. Not quite as lean as fleet, but still small.

Ultimately, I'll probably end up replacing the intake and exhaust with
some of Jack Clifford's spicy stuff

Or not. Be very careful before you decide to spend any money with Clifford. They have a long and ugly reputation for being a bunch of clowns; see for example here, here, here, here, and here. Much of what they sell is inaccurately described, and a lot of it is not even slightly cost-effective. The good news is that you don't need to go to Clifford to get hot rod parts for slant-6s; there are lots of other, better options. See for example Dutra Duals and header options discussed in this thread and this one, Erson custom cams, HEI ignition upgrade, Mike Jeffreys windage trays, Hurricane intakes, other exotic intakes. Hi-perf engine buildup here, high-perf parts and build info here.

How hard do you think it would be to find a 2 barrel that would accept the rotating rod style throttle linkage?

No such carb exists; you'd have to make one by modifying a cable-type 2bbl (and modifying an intake as described in See the parallel 2bbl setup article. Photo documentation of a very well done such conversion is here (if that link still works).

Or you could swap in a cable-type accelerator...
