I've had past experience with the referee system, I put a 96 454 engine and trans (w/all wiring) in a 95 Chevy p/u. That was a change from obd1 to obd2 and required a referee inspection and approval. It really isn't that difficult, DMV has a list of referee's you can use, call them explain what you are doing and if it within their purview, they will schedule an appointment to bring your vehicle for the inspection. If you pass their inspection you take it to a smog test station for testing, bring your successfully completed inspection back to them and they issue you an approval w/your changes.

I believe the key to passing w/aftermarket headers and cats is getting the cats to a high enough temperature to allow them to convert. Of course that assumes all the stuff on your engine functions as its supposed to. The aftermarket cat system will not cover other systems not functioning properly like the factory cat will.
