Best For others: Edelbrock heat Insulator

Buy on Amazon

Compared with other gasket in this category, the edelbrock heat insulator has a convenient design. Edelbrock has one side of this heat insulator that is not finished with the rubber coating very well at all. It keeps the carb cooler and helps avoid the gas boiling when you shut down an engine that is at operating temperature. This is like an extremely thick gasket. The rubber coating on the outside of this thing is what really seals it to the carb and manifold. The unit acts as its own gasket.

This is a gasket just very thick and works realky well. It does it's purpose by keeping the fuel/air mixture cooler on otherwise hot running engines preventing "percolating" of the fuel. These gaskets stop vapor lock.
