Ferrea Chevrolet SB 1.6in 11/32in 5.46in +.500 Super Alloy Exh Valve - Single (Drop Ship Only)

This Ferrea exhaust valve features a 1.6-inch face diameter and is constructed from Super Alloy, a material chosen for its strength and resistance to high temperatures found in exhaust ports. The valve stem measures 11/32 inches in diameter, and the overall length is 5.46 inches, designed to be 0.500 inches longer than a standard valve. This specific sizing and material choice are important for engines that have been modified or rebuilt, especially in Chevrolet Small Block applications where improved airflow and durability are key.

The Super Alloy construction helps this valve withstand the harsh conditions of the exhaust cycle, resisting warping and wear even under significant heat. Its +.500 oversize dimension means it's intended for engines that have had their valve seats machined to accept a larger valve, which can help improve cylinder head flow and overall engine performance. Ferrea is known for making well-built valvetrain components, and this exhaust valve is a solid option for builders looking for reliable parts for their performance engine projects.
