6 pack Drivability Modifications

Hey guys,
I have a NEW 340-6 pack set up and I have read some blogs that mods need to be done to them for air mixture accessibility and possibly some sort of power valve issues or changes. This is a street 340-372" with 469hp and 493 lbs of torque, but I'm not interested in putting any more power to the motor, just good drivability. What do you guys recommend and where do I get the parts from?
Martin
