1/2" Base to Upper Spacer Plate Kit for Perf. & Perf. RPM 5.0 Manifolds

Edelbrock Wood Fiber Laminate 1/2" Base to Upper Spacer Plate kit for Performer and Performer RPM 5.0 Manifolds PN's 3821 and PN 7126. Includes spacer plate, gaskets, and bolts. Used to increase valve cover to upper plenum clearance.
PN 8727 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 accomodate 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. As a third benefit the 1/2" extra runner length helps to produce more torque. Fits all Performer 5.0 PN 3821 and PN7126 based manifolds.
