I think that you will need to have an LSA of at least 117-118 in order to maintain idle and pass smog without problems. By having the higher LSA you will be able to keep your stock torque converter and add more duration and lift. I would recommend a 117-118 LSA with 224 Duration and .591 Lift. You will need a better set of Valve Springs like the Comp Beehive 918 and Titanium Retainers. This cam will be real strong normally aspirated and also be a monster cam for the MagnaCharger later, if you so decide.
The Cam above will be a special grind that you can have done at Comp for about $395 then you should use a Double Roller Timing Chain, Ported Oil Pump, Oil Pump Spacers, Comp 918 Springs, Titanium Retainers and a set of 1.7 Ratio Shaft Rockers to top it off.
That Transmission will be the weak point in the build. The 05-06 SSR Automatics are finding that out real fast once they start to mod. The Torque Management alone makes a huge difference with the LS2's. If you can get a transmission built by FLT (Stage 4 or 5) you could remove the Torque Management.

The 4L70 is still weak behind the LS2, especially if you start removing the torque management.
California would never pass a vehicle with a 112 LSA. Lucky you are not out here I guess.

I'd recomend the Comp Cams XER273HR. A friend is running that with his LQ9 and Dart 225's. It idles fine at 650 and still has the stock stall. His 60' times are the same as stock and it pulls great from there on out.
