REPRODUCTION. You are purchasing 1 pair of valve covers. These are available in a "As Cast" finish, "Polished" finish, or "Black Powder Coated" finish. Please select from the drop down menu to select the finish. These have a heavy duty sand-cast aluminum construction. These valve covers are perimeter mount, with four bolts per cover, included. These do not work on engines that require center bolt mounting. The open interior clears most roller rockers, please double check the measurements below to ensure proper fitment. These are a thick wall construction with gasket flanges that will not bend or flex when bolts are tightened for a leak free seal.
These valve covers include the correct mounting hardware. The gaskets are not included, if you would like gaskets added to your cover, please select from the drop down menu.
Most applications breathe through the valley plate so these valve covers do not incorporate a provision for breather holes or PCV. If you would like this option added please contact us directly after your order is placed.
