PROFORM 141-257 GM LS-Series Slant-Edge Tall Baffled Valve Covers with Breather Holes, Orange

Upgrade the appearance and functionality of your GM LS-Series engine with PROFORM 141-257 slant-edge valve covers. Designed with a tall profile and integrated baffling, these aluminum valve covers provide added clearance and help control oil mist within the valve cover area. The raised LSX logo and orange powder-coated finish create a distinctive engine-bay appearance while providing a durable surface for long-lasting use.
These PROFORM valve covers feature built-in breather holes to support crankcase ventilation when used with compatible breather components. The slant-edge design complements a wide range of custom and performance-oriented LS engine builds, while the lightweight aluminum construction offers dependable strength without the added weight of heavier materials. The pair configuration provides matching coverage for both cylinder banks.
Designed for GM LS-Series applications, PROFORM 141-257 valve covers are a practical choice for street, show, and performance vehicles. Verify engine configuration, rocker arm clearance, breather requirements, and accessory compatibility before installation. The covers are supplied as a pair and are finished in orange powder coat for a clean, coordinated appearance.
