Carburetor suggestions for 318

Gears are 3.23. the torque converter is factory, but the transmission has been rebuilt with a shift kit. I bought the heads from Aerohead racing. The heads work pretty decent but I'm sure I'll upgrade them at some point. The car isn't sluggish or slow, I just wondered if I could optimize my performance and get rid of some of the hesitation with a different carburetor. I'll visit the edelbrock website and read the owners manual.
