When I imported my 71 1600 Cab from Belgium to CA, I was worried about the DMV dealing with the foreign paperwork. I actually ended up using one of the Title transfer services to get a New York title and then took that to the DMV. Pre-1976 (30 year old cars) are exempt from the smog test, so I paid my fees and was told that I needed a vehicle inspection report from the CHP. You get the special forms you need, make an appointment, take your car down and they check it to make sure the Vin numbers are intact and the car was not stolen or re-assembled with stolen parts. They weren't concerned about any of the original smog equipment.
California laws are changed frequently, so I would save anything related to the original emissions for re-installation. You never know...
