Stumped and Frustrated with a Holley 670 Hesitation

Well after a 40 minute wait time, I got to talk to Holley tech support. The gentleman I talked to said it sounds like my accelerator pump nozzle is sized to small and I should increase it from a 31 to a 35.

As for the whistle sound, he said that is caused from a carb gasket hanging over and in the air stream. Said it didn't hurt anything, but that is whats happening. So I have a question about that. Im running the edelbrock 5/16" heat insulator gasket and I also installed a paper gasket on the top and bottom of that. It didn't say to add them or leave them off so I added them. Should I take them out?

So off to the local carb shop to pick up a bigger pump nozzle and trying that. I hope that is all it is.
