SBC C/P HS 1.500 Exhaust Valves 4.910 OAL

The SBC C/P HS 1.500 Exhaust Valves 4.910 OAL from FERREA are precision-engineered components designed for small-block Chevrolet engines undergoing serious performance modification. These exhaust valves are essential for ensuring reliable, high-flow exhaust gas evacuation in modified cylinder heads, particularly those with ported or competition-level work. Whether you're building a street cruiser with mild port work or a dedicated race engine, quality exhaust valves are foundational to consistent power delivery and engine longevity.

FERREA's reputation in the aftermarket stems from strict manufacturing tolerances and material selection that resists thermal cycling and combustion chamber stress. The 1.500-inch head diameter on these SBC C/P (small-block Chevrolet, conventional port) valves provides the flow area necessary for optimized exhaust scavenging, while the 4.910 overall length (OAL) ensures compatibility with standard small-block Chevrolet configurations without requiring stem modifications. The stainless steel construction and precision grinding deliver consistent valve-to-seat contact geometry, reducing leak-by and maintaining proper combustion chamber sealing across thousands of heat cycles—critical for both naturally aspirated and forced-induction builds.

These exhaust valves are ideal for builders upgrading cylinder heads with performance cam profiles, dual-plane or single-plane intake manifolds, or header systems. When paired with matching intake valves, they contribute to a well-rounded performance setup that maximizes engine efficiency and power output. Builders looking to enhance their small-block Chevrolet engines will find these valves to be a reliable choice for achieving their performance goals.
