The only external identification difference between an LS1 (normal Z28, WS6, C5) and the LS6 (ZO6 only) is red valve cover covers (that do not fit under a F-body hood), a slightly larger plenum (still black plastic), and the 85mm mass airflow sensor.  The differences are the cylinder head castings, valvetrain, intake and exhaust systems.  Very expensive parts, and uncommon.
