77cruiser:
With holes in the plates you're passing more air through the venturis & increasing chance for nozzle drip. Either way you are going to need to richen the idle circuit.

what Cruiser said.
Holley guys can get away with drilling the plates because their boosters are not as sensitive as Q-jets.

I have Cliff's book and I read why but I'm unclear of how to richen the idle circuit. Could you explain it?

Please disregard. I found the info in Ch. 6. I must admit I'm nervous about this mod and messing up a decent carb.
