Piece of cake. You need:
1. Bigger main jets, duals don't like to run anywhere near lean or even normal. They like rich. You might consider the power valves as well, they should be at least 1/2 of whatever your idle vacuum reading is. Idles at 12"? 6" PV's or even 5's.
2. Bump up the base timing, very common to not run enough. Should be at least 14, I'm running 20.
3. More cowbell, oh wait, that was another thread...
