It's not starving for fuel, it's flooding most likely from fuel boiling in the bowls. insulated carb spacers may help.

"Do they sell stock material that you can cut yourself. Should I make these as thick as possible to fit under hood? Maybe 1, 2, or 3". I do have room."

Yes, they sell sheet stock if you want to make your own. Usually, you want just 1/4" as raising the spacer height may play with plenum volume.
