Best Bang for the Buck Head???

Thanks for all the input guys. They heads are fresh and the motor runs well. Just looking for a bit more power.

Right now, I've got 2 carbs (1406 600 Eddy and a 4779 750 holley dp) and 2 intakes (Eddy torker and Eddy RPM air gap) and a 1" spacer. What intake/carb combo do you guys think would run best???
