SBC S/D 2.020in Intake Valve

The SBC S/D 2.020in Intake Valve from Manley is designed specifically for small-block Chevrolet engines, catering to engine builders, street performance enthusiasts, and racing mechanics who prioritize precision and reliability. This valve is essential for those involved in rebuilding classic 350 engines, tuning modern LS platforms, or restoring vintage performance engines.

Featuring a head diameter of 2.020 inches, this intake valve is engineered to optimize the intake of fuel-air mixtures while ensuring a proper seal against the valve seat. The valve stem diameter and length are manufactured to precise specifications, which are critical for maintaining clearance with rocker arms and pushrod geometry, thus preventing binding and wear during high RPM operation.

Ideal for anyone undertaking a complete small-block Chevrolet top-end rebuild or upgrading cylinder head assemblies, this intake valve supports improved cylinder head compression and combustion efficiency. Proper installation requires attention to valve seat angles and stem-to-guide clearance, ensuring optimal performance in various applications.
