Up and running! Reused the 2000 manifold and wiring harness, plugged the hole for the EGR tube on the '03 head with a threaded plug from the dealer. One MAJOR snag... I discovered AFTER getting it all reassembled only to have a no start issue, That Crank and Cam sprockets were Totally different! Having different trigger points confused the ECU to say the least. Tore the front off again swapped the sprockets, from the 2000 onto the 2003 and VROOM! I'm good to go.
