BIG-BLOCKS VALVE COVERS

Top off your high-performance Big-Block with a pair of Chevrolet Performance valve covers. These precision-fit valve covers come in a variety of finishes and colors and are made out of die-cast aluminum or heavy-gauge stamped steel. Quality construction methods help provide good sealing and low chance of leakage from deflection caused by overtightened fasteners. Competition valve covers are designed to clear taller valvetrains.

NOTE: Valve covers are sold in pairs unless otherwise specified.
