I don't know much about Guzik, but I recall reading where Fed Bureau of Narcotic agents spotted Accardo and Guzik boarding a plane together (about late 1940's) and attending meetings at a restaurant in NJ with other mob bosses in attendance. They supposedly made multiple trips together. My guess is the meetings had something to do with west coast activities (perhaps Bugsy?). Guzik was considered one of the Big 6 at that time.
