They all come with it (except Haruna). In normal situations (normal morale, no combined fleet, decent level) overweight penalty from 41cm is about 1-2% (same as one point in accuracy), so it's fine to use them (lets say two), radar/AP compensate this penalty and if you improve 41cm it can actually give a bonus rather then penalty.
