SBC S/D 2.055in Intake Valves

The SBC S/D 2.055in Intake Valves by Manley are designed for serious small-block Chevy builders and performance enthusiasts. These valves are ideal for high-flow cylinder head applications, ensuring optimal airflow and reliable sealing at high RPMs. Whether for street performance or competition engines, they provide the durability and precision needed for modern builds.

Engineered with a 2.055-inch head diameter, these intake valves optimize airflow while maintaining structural integrity. Made from valve-grade stainless steel, they resist oxidation and thermal fatigue, making them suitable for various fuel types, including pump and race fuels. The precise stem geometry and face angle enhance sealing performance, reducing blowby and supporting tighter chamber tolerances.

These intake valves are particularly beneficial for small-block Chevy applications that utilize modern cylinder head designs, especially those with larger bore diameters or ported aftermarket castings. Their robust construction and performance characteristics make them a reliable choice for builders looking to enhance engine performance and efficiency.
