Holley® 241-137 - Muscle™ Valve Covers

Muscle™ Valve Covers (241-137) by Holley®. These new products are the 1st of the Vintage Series family of die-cast aluminum dress up products featuring a classically inspired finned design and a retro-style Holley script brand mark. Holley’s tall LS valve covers (for Dry Sump Applications) are the latest addition to their extensive line of LS engine components that will add a custom touch to your engine bay and help you to stand out from the crowd. These valve covers were designed to add an additional 0.54” of internal clearance over factory height valve covers. The valve covers retain Holley’s signature integrated angled coil mounts, and the hi-tech look and performance of coil-on-cover applications. The Holley tall LS valve covers fit LS1, LS2, LS3, LS6 and LS7 engines using coils with a standard LS3 bolt spacing of 72mm.
