Carb Heat Soak

Looking for a good spacer/gasket recommendation to reduce heat soak on my carb. Current set up is an Edelbrock 650CFM AVS2 carb and performer intake on an LA 360.
Along with the Edelbrock 9266, I also recommend blocking off the intake manifold exhaust cross over. That will greatly reduce the intake manifold temperatures under the carburetor. Since you're in Florida, you'll see very little if any cold starting changes.
