Holley 241-91 Details

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. Or, paint to match your vehicle's theme!

Bought these for an LS swap I'm doing on a 57 Chevy. They look great and get rid of those coil brackets. Worth the extra money.
