The float bowl pressure should be equalized, that's what those two pipes sticking up out of the air horn are for, they vent to the inside of the air filter, thus keeping the pressure inside the air filter and inside the float bowls equal.

A fuel pressure of 8-9 is WAY too high for a holley. Max should be 6.5. You need a regulator. Are you running a mechanical fuel pump or electrical?
