Edelbrock part #8729 spacer kit includes a 7/16″ thick spacer and two .045″ thick gaskets for a total thickness of 1/2″. The kit also has new base to upper fasteners to accommodate the spacer. There are several benefits to the kit. First it raises the upper manifold 1/2″ for increase valve cover to upper plenum clearance. This is needed to run a taller cover such as when roller rockers are used. It also provides heat insulation between the lower and upper manifolds.
