"They are for the crossover that runs under the carb. They will restrict the amount of hot air that runs under the carb to heat it in cold weather operation. At least I hope that is what you are talking about!!!"

kcress, the exhaust gases pulse into the chamber under the carb from each head, heating the manifold to help atomize the fuel/air mixture. You'll be glad you have 'em on a cold morning on a street-driven car. The guys who mainly drag race with their cars plug them so that the mixture will be cooler and thus denser.
