Carter AFB 4312

I am fixin to rebuild a carter AFB number 4312 for a 67 440.

I scored the carb as a core from a fabo seller and the engine came out of a 67 GTX. (stock specs and still a strong runner)

The carb number comes back for a 67/440 auto California.

I would like to know what the "California" part means on the carb.

Any AFB gurus out who can tell me any little tricks or things to expect

I was going to get a kit from auto zone made by GP Sorenson which has all new gaskets/pump thingy and float gauges. The core is very decent and everything moves around freely. I have put kits in carbs before so I am not a stranger to having a carb apart, however this is the first time I am messing with an AFB. I have fiddled with a lot of Thermoquads successfully so far.

Is there anything I can do to this AFB carb to make it reliable or anything to watch out for?
