Chevy LS Billet Valve Covers - Extra Short - Black Anodize

Upgrade your LS engine with March Performance Billet LS Valve Covers, precision CNC-machined from solid 6061-T6 aluminum for exceptional strength, durability, and a premium appearance. Designed to fit all Gen III and Gen IV Chevrolet LS engines, these extra-short valve covers combine performance-focused engineering with clean styling and dependable, leak-resistant sealing.

Unlike stamped or cast valve covers that rely on removable sheet-metal baffles, these covers feature machined-in-place internal oil baffling. The integrated dual-baffle design eliminates loose baffle screws or fasteners that could potentially work free over time, providing a durable solution for street and high-performance LS applications.

Each kit includes premium molded valve cover gaskets and stainless steel self-sealing socket head cap screws with captive Viton® O-rings. The integrated sealing system eliminates the need for separate bolt grommets or washers while providing a clean, leak-resistant installation.

For custom crankcase ventilation, each valve cover features dual -12 ORB ports with your choice of -10AN or -12AN adapter fittings. This allows for flexible PCV, breather, catch can, and oil fill configurations. Due to the extra-short design of these LS valve covers, the included fittings are required for proper setup.

Designed and manufactured in the USA, these billet valve covers are an excellent addition to high-end LS engine builds and pair perfectly with March Performance serpentine systems for a clean, coordinated engine compartment.
