Modern Classic Series 409 Chevy Style LS Valve Covers
Modern Classic Series 409 Chevy style valve covers are designed to give the appearance of an early 1960's 348 or 409 Chevy, while fitting the LS family of engines. Like all LS Classic 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 2.750 in. tall. 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 castings are designed to be thick enough for drilling and tapping for fittings. Covers are available with a natural cast finish, chrome plated, painted Chevrolet orange or 409 champagne, all with vintage 409 Turbo-Fire factory stickers. The covers have no provision for oil fillers and can be used with Modern Classic Series valley plate with an oil fill tube. Order the valve cover in the finish you prefer.
