Each valley cover is custom machined for either LS1/LS6 (10 bolt) or LS2/LS3/LS7/LSX (11 bolt) patterns and Holley / Mr. Gasket offers all the necessary gaskets and upgraded hardware options to complete your installation. The new finned LS valley covers are available in five unique finishes: natural cast, polished, satin black machined, factory orange machined, and gloss red machined.
