Brian,

Michael is right. Holley carbs pull secondary vacuum through the high pressure side of the venturi (within the carb) If yours are not opening you need a lighter spring.

What carbs are you using? Where they prepared for a dual quad engine specifically or are they "out of the box" 1850's or similar?
