Holley's tall LS valve covers are the latest addition to our 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. These 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 (coils not included). These valve covers come ready for installation with an OE style baffle and ventilation system, lengthened factory style mounting hardware, plus a billet aluminum oil fill cap.
