I concur with Jerry on what he said above. The dual Weber carburetors are another story. If you want to improve the carburetion of your engine, please keep the same stock manifolds (both of them) and change your carburetor to a Carter YF model. There are a bunch of reasons it is better than the Rochester. We've slaughtered millions of electrons here discussing it and the correct answer always comes up the same. For your year 235 a YF2100S or a YF2101S would be what you need. The 2100 has a manual choke (not so easy to find now) and the 2101 has an automatic choke (which many of us prefer...Jerry and I are in that auto-choke crowd). As for dual carburetors the best answer I've heard is that you have either one too many or you need one more (like the 3 the Corvette 235 used). Or you might be able to rig up a scheme where 3 motorcycle carburetors could be used. Good luck!
