2004-2007 Cadillac CTS-V Valve Covers & Accessories

Katech designed and manufactured a cast aluminum valve cover for the LS1 and LS6 engines. These covers are a raised design which allows clearance for any LS1 style rocker arm. Unlike the C5-R covers, these use the stock gasket for sealing. This eliminates the expensive cylinder head o-ringing process. Just like the stock covers, these are totally isolated from the head by rubber. That means they will seal just as good as the stock covers do.

Another key feature is provisions for coil relocation brackets. These brackets allow the coils to be mounted off the top of the cover. This makes taking the covers on and off easier by removing the cover and coils as one piece instead of two for solid lifter valve lash adjustment.

Moroso Fabricated Aluminum Valve Covers come TIG welded and CNC manufactured to eliminate distortion and ensure a prcise fit. Fabricated entirely from aluminum - ultra lightweight at less than 2 lbs each. One piece rigid gasket rail provides a precision-flat surface for superior sealing. Air-tight sealing allows the engine to pull greater vacuum for improved ring seal and power. Tall enough to clear all popular race combinations. Notched at each mounting location with socket-sized clearance for quick installation and removal.

• One-piece Billet Rail is CNC machined from 6061-T6 Aluminum to ensure a precision flat surface for superior sealing
• 2.5" tall to clear aftermarket valvetrain
• Oil Fill Bung welded to cover, knurled cap included
• O-ring Seal Groove
• Uses stock type o-ring

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 give 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.
