2-Pc LS "Chevrolet" Script Valve Covers "Factory Orange Machined Finish

Cast Aluminum LS Valve Covers with Coil-Mounting Base & Integrated Coil Cover

Holley's new 2-Piece LS valve covers are a great way to update the look of your LS engine without the use of complicated adapter systems or the hassle of remote coil relocation. These modular LS valve covers feature an OE height, internally baffled LS valve cover base with integrated coil mounts for popular Gen I and Gen V style LS coil bodies, and a "Chevrolet" branded overcover that hides the unsightly LS coils and messy wiring harness - allowing the full performance benefits of coil-on-cover ignition setups without the robotic styling. Each modular coil cover features a prominent vintage "Chevrolet" logo that matches various other GM licensed Holley products. The coil cover also features cast-in provisions for the spark plug boots and coil wiring harness so no extensions or custom wiring is required.

Each 2-Piece LS valve cover set includes a low-profile billet oil fill cap, hardware and spacers for mounting both versions of LS coil bodies, and 12-point dress up hardware and rubber grommets for the coil covers. These modular LS valve covers are available in 5 unique finishes: natural cast, polished, satin black, factory orange, and gloss red (black, factory orange and gloss red sets feature machined fins).
