Nothing if you can get the car registered as a 1966.

Hello:
I just went through this. If you don't have your car registered as a 1966, and it is a (SPCNS) "Special Construction" , get ready. CA smog will look for a PCV, and will go by engine year. Just tell them it is a 66 engine block, and they won't really check it.

Connect a PCV to your valve cover breather cap. I bought one for the test. Plug off all other escapes. I had to: Jet my 750 vacuum sec carb as low as I could go, drop from a 165 to 145 power valve, and retard the timing as low as I could go -3 degrees. Run a bottle of "Guaranteed to Pass" in the tank before you test; obtain at Kragen. Shhhhh. Once done, I switched it all back, and gave the smog kit to the new owner. The last I learned is I only needed to smog it for transfer, (for DMV to verify it is not a gross polluter) but never had to smog it in 4-years of owning as a SPCNS car because the engine was coded on the CA BAR tag as a 1966 7.0 litre V8. I hope this helps.

If you choose to eliminate the return exhaust portion on your heads you will need to purchase some 1/2 " 20 threads per inch tubing plugs. They are about $.25 each. Good luck.
