The Edelbrock Carburetor Spacer #8722 divided design is for use with Dual-Plane design intake manifolds. The Edelbrock #8722 divided spacer is 1/2" thick and made of wood fiber laminate. The superior heat insulating properties of wood fiber laminate are ideal for reducing heat transfer to the carb.
The cure for hot soak flooding and vapor lock, this will keep your carb cool! And in my case, allowed me to use the correct choke thermostat for my intake manifold.
