Actually, the people who market the hyper charger have spacers for just about anything. The swain coatings would certainly help, but the proximity to the heads has more to do with it, if you don't believe me grab an engine part that has been swain coated right after you shut the motor off, (ouch!) Getting that big backing plate away from the heads lets the heads get rid of heat a lot faster too, which in turn helps the motor run cooler, etc.
My 1200 Buell Lightning runs damn hot because of the way it's perimeter gas tank/frame holds heat into the head fins, If it weren't for the cooling fan, air scoops and ECM settings it would melt down, especially in AZ in the summer.
