The heads from the CEP initial release stripped out for use in your override directory to allow for custom head selection in multiplayer games and single player modules without the haks loaded. No modifications have been made to any of the files, they were simply extracted and repackaged. This was requested by some people on the Bioware forums.
Update 08/01/04: Added Orc heads (sorry for missing them) Update 10/27/04: Revised with CEP 1.50 corrections, removed extra file.
