While technically this is true, no one actually cares. If the chassis is pre-smog, then you don't have to smog it.
The exception to this would be if you're in an area where cops regularly pop hoods on imports and your the type of person who encourages such encounters with the local law. In that case, being 100% above-the-board legal might actually save you some headache.
