Holley’s tall LS valve covers dress up your engine bay and add an additional 0.54” of internal clearance over OEM to clear taller valve train components in high-horsepower applications. The Holley tall LS valve covers fit LS1, LS2, LS3, LS6 and LS7 engines. These valve covers come ready for installation at Marken Performance with an OE style baffle and ventilation system, lengthened factory style mounting hardware, plus a billet aluminum oil fill cap. (Customers are encouraged to reuse or replace the original gaskets specific to their application.)
The plain tall valve covers retain Holley's signature integrated angled coil mounts designed for standard LS3 coil bolt spacing of 72-73 mm. The Dominator valve covers eliminate the coil-on-cover mounting provisions for the ultimate clean look in LS applications with an aftermarket distributor conversion or relocated coil packs.
