Just means they can run a wild cam for power higher in the revs, and have a less wild section of cam for a nice idle etc.
The reving to 9k is to do with the valvetrain components - you could rev to 9k on a 16v vts engine, but would need a lot spending on the engine so it was safe reving this high.
Remember though that parts will wear quicker at the higher rpms.
