Performer will work better than the Torker. The Torker is more for high rpm applications. I think there is EGR and non- EGR intakes. Double check before buying.
No clue on CA smog, I've never had to deal with smog and never want to. If you painted the intake and got a CARB sticker for the TBI you could see what happened. Some smog folks are kinda clueless I guess.
Yes you would need an adapter, Performer is 4bbl intake, TBI is two. I don't think they are that expensive and there are some options, so shop around.
I imagine you know that the 454 TB bores are bigger (2") than a small block one (1 11/16" I think) and would probably better suit a 401. The 454 TB is about 600 cfm last I remember.
Hope this helps. Ask more questions if you need to.
