All zed cam shells are the same size right up to the gpz's. They didn't do undersize or oversize options from the factory. The upper half ones usually wear the most as their always subject to valve spring pressure. It will be fine fitting a good used one as long as its not worn through the white metal or badly scored. Don't try reaming them as it will turn them to scrap.
