{"title":"LS\/LT Heads and Valvetrain","description":"\u003cp\u003eShop high-performance LS and LT cylinder heads and valvetrain components designed to improve airflow, increase horsepower, and enhance engine efficiency. From camshafts and rocker arms to lifters and valve springs, these components help optimize valve operation and overall engine performance. Ideal for LS and LT engine swaps, street builds, and high-performance applications.\u003c\/p\u003e\n\u003c!--split--\u003e\n\u003cp\u003eThe cylinder heads and valvetrain are essential components of any LS or LT engine, responsible for controlling airflow into and out of the combustion chamber. Proper valve operation directly affects engine performance, efficiency, and power output. The valvetrain system works by transferring motion from the camshaft to the valves, allowing precise timing of intake and exhaust events.\u003c\/p\u003e\n\u003cp\u003eLS (Gen III\/IV) and LT (Gen V) engines use a pushrod overhead valve (OHV) design, where the camshaft is located in the engine block and motion is transferred through lifters, pushrods, and rocker arms to open and close the valves. This design offers a compact engine size while maintaining excellent durability and performance.\u003c\/p\u003e\n\u003cp\u003eKey LS and LT valvetrain components include camshafts, lifters, pushrods, rocker arms, valve springs, and cylinder heads. The camshaft controls valve timing and lift, while rocker arms transfer motion to the valves, opening them at precisely the right moment to ensure efficient airflow and combustion. \u003c\/p\u003e\n\u003cp\u003eUpgrading cylinder heads and valvetrain components is one of the most effective ways to increase horsepower and improve engine performance. Performance camshafts can increase valve lift and duration, allowing more air and fuel into the engine, while upgraded valve springs and rocker arms help maintain stability at higher RPM levels.\u003c\/p\u003e\n\u003cp\u003eHigh-performance cylinder heads are designed to improve airflow through larger ports, optimized combustion chambers, and improved valve design. These upgrades enhance power output and efficiency, especially when paired with supporting modifications such as intake and fuel system upgrades.\u003c\/p\u003e\n\u003cp\u003eIn LS and LT swap applications, properly matched heads and valvetrain components are critical for achieving reliable performance. Upgrades such as camshaft packages, lifters, and pushrods are often selected together to ensure compatibility and maximize performance gains.\u003c\/p\u003e\n\u003cp\u003eLS and LT heads and valvetrain components are especially important in performance builds where precision, durability, and airflow are key. Whether you're upgrading a stock engine or building a high-horsepower setup, choosing the right components helps ensure improved performance, efficient combustion, and long-term reliability.\u003c\/p\u003e\n\u003ch3\u003eShop Related LS \u0026amp; LT Components\u003c\/h3\u003e\n\u003cul\u003e\n  \u003cli\u003e\u003ca href=\"\/collections\/ls-lt-engine-components\"\u003eLS \/ LT Engine Components\u003c\/a\u003e\u003c\/li\u003e\n  \u003cli\u003e\u003ca href=\"\/collections\/gm-ls-lt-intake-manifolds\"\u003eLS \/ LT Intake Manifolds\u003c\/a\u003e\u003c\/li\u003e\n  \u003cli\u003e\u003ca href=\"\/collections\/ls-lt-air-and-fuel-delivery\"\u003eLS \/ LT Air \u0026amp; Fuel Delivery\u003c\/a\u003e\u003c\/li\u003e\n  \u003cli\u003e\u003ca href=\"\/collections\/ls-lt-ignition-and-power\"\u003eLS \/ LT Ignition \u0026amp; Power\u003c\/a\u003e\u003c\/li\u003e\n  \u003cli\u003e\u003ca href=\"\/collections\/ls-lt-front-drive-systems\"\u003eLS \/ LT Front Drive Systems\u003c\/a\u003e\u003c\/li\u003e\n\u003c\/ul\u003e","products":[{"product_id":"gm-lt-cast-aluminum-valve-covers-with-coil-mounts-polished","title":"GM LT Cast Aluminum Valve Covers with Coil Mounts - Polished","description":"\u003cp\u003e\u003cstrong\u003eGM LT Cast Aluminum Valve Covers with Coil Mounts Polished for Sealing, Clearance, and Engine Bay Detail\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp\u003eThese GM LT valve covers are built around the details buyers search for most: fitment, valve cover height, material, finish, ventilation, and sealing.
