Didn't mean to take this on a tangent, sorry. Hope you found the problem you were looking for!
i think you could do most of the flow mods and have something that passes.
for instance, you could use the smaller throttle plate screws, and cut the throttle shafts down, and you could smooth the parts on the main body that are wonky. you can certainly ditch the choke. you could also do the secondary venturi, although i think the primary venturis the jetting, and the carb linkage and emissions stuff would stay stock.
