Another method that may work, but probably not as well as the last mentioned, is to do analysis>minimum radius, and select all the faces in question. It will show you the smallest radius face, but not all the faces of smaller radius. So if you are changing these face radius' you could do this one by one. Tedius and probably not worth it, but another option.
