The Edelbrock Dual-Quad heat insulator gasket kit (#9267) prevents percolation on Thunder Series and Performer Series carburetors exposed to high under-hood temperatures. Its four-hole design allows dual-quad Performer and RPM manifolds to seal properly to the carburetor. Installation requires replacing short carb studs with longer studs; the kit ships to position the gasket directly against the manifold and restore proper insulation.
