Using new head bolts when performing a cylinder head installation is always a good idea however, on late-model engines that came from the factory with TTY (torque-to yield) head bolts, replacement is an absolute necessity. TTY bolts are designed to exert the maximum clamping force for a tight head gasket seal, however they permanently stretched and could fail if re-used.

Let’s face it, nobody wants an ugly set of ignition coils sitting atop their newly dressed up engine. You can take the time and effort to relocate them or you get a set of TSP’s two-piece valve covers. The base has a tall internal height to allow for added valvetrain clearance and features provisions for mounting two of the most popular LS coil packs – no brackets required. It also features a baffled stock-style ventilation set-up. The coil cover features cut-outs for routing the wiring harness and spark plug wires and comes with a smooth top.

“Holley’s cast aluminum valve covers for GM LS engines provide a fresh, refined look without the need to relocate the coils. There’s no question the factory “”coil on cover”” design gives the LS that signature high-tech look, but the factory brackets and coil location leave room for improvement. Clean up that signature look with Holley’s LS Valve Covers! They incorporate a radiused shape, angled coil mounting, and a billet fill cap. Plus, the coils mount directly to the cover with no need for a bracket in-between. They fit most popular LS series engines and come in Black Krinkle, Satin, Natural Cast, and Polished. Or, paint to match your vehicle’s theme!”

This replacement valve cover matches the fit and function of the original equipment part that may be damaged or warped. Made from quality materials for excellent fit and superior heat resistance, this valve cover has undergone extensive testing.

“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. 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 (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.”
