Poor throttle response

Need you guys suggestions.
I have
30 over 440, 12.5 to 1, reworked eddy rpm heads, team G intake, quick fuel 850 carb,2" primary tube headers, 4500 stall converter, 456 gears
solid lifter cam, H&S roller rockers (see cam specs)
Problem engine runs great mid and high range, off idle I have to feather the gas. I want to be able to just nail the pedal and go.
Some of you suggested I need to go to a eddy rpm manifold. I think I'm in agreement with that.
Do I need to change cams as well?
