We have to run a rochester 2 bbl with a restrictor plate and I was told that if you run a smaller base plate on that carb then you could pretty much get around the restriction caused by the plate, can anybody clear this issue up with me?

I think what you'll find is that if you ran a baseplate that had the same bore size as the restrictor plate you run, that the turbulence, reversion, and poor flow efficiency will be less than if you ran a larger baseplate with a small hole'd restrictor.
This is NOT to say that you'd necessarily make more power by running a small baseplate, only that perhaps the throttle response would be smoother and the unbalanced cylinder EGT's, etc will be lessened a bit.
The top end will still be chopped down similarly tho.

Just my opinion, of course, hope it helps.
