Dual quads versus big hammer!!!...

If you own a normal holley you have them gasket on hand or you don't adj the fuel level.
Just like pulling the top off of your carb. and it was prone to brake the gasket, you would have a spare one before you took the top off to set the float.
They're not made out of paper gasket like the Edelbrocks and Holley's, they have a rubber reusable gasket again above all gas levels..
