Post Weber carbs that boil

I'm running four Weber carbs, and recently changed over to aluminum heads. The carbs now seem to boil the fuel in the float bowls much easier than with the iron heads. Is the heat problem directly related to the improved heat transfer of the aluminum heads?

Most likely, a shield will help. Webers have such tiny fuel bowls this problem will get worse with aluminum heads.
