    Our LS Classic Series Big Block Chevy Style Valve Covers are designed to give the appearance of a big block Chevy while fitting the LS family of engines. Like all our cast aluminum valve covers, they accept the OEM rubber seals (not included) and bolt directly to the cylinder head. With No extra adapter required, there is less chance of leakage and the covers are only 2” tall. The valve covers include a billet aluminum filler cap on one cover for easy oil filling. The covers come with all the necessary mounting hardware, including factory look load spreaders, and have a ported PCV fitting/vacuum port and oil splash baffle in one cover. The casting is designed to be thick enough for drilling and tapping for fittings. Covers are available with a natural cast finish, chrome plated, or painted Chevrolet orange and include vintage Chevrolet Tonawanda factory stickers.
