SBC OEM Style 1.500in Exhaust Valve

The SBC OEM Style 1.500in Exhaust Valve from FERREA is engineered for Small Block Chevy engines requiring factory-specification replacement valves that meet or exceed OEM performance standards. Whether you're rebuilding a stock engine, restoring a classic muscle car, or assembling a high-mileage block back to original spec, this exhaust valve delivers the precision and durability that serious engine builders demand. Designed to work seamlessly with OEM-style cylinder heads, it eliminates the guesswork when sourcing quality replacement components for your SBC platform.

Machined from premium stainless steel, this exhaust valve features a 1.500-inch head diameter and an 11/32-inch valve stem, matching Small Block Chevy OEM dimensions precisely. The 4.910-inch overall length ensures correct seating depth and proper rocker arm geometry when installed in compatible cylinder heads. Stainless steel construction resists corrosion, withstands thermal cycling, and maintains dimensional stability across repeated heat cycles—critical factors for both street-driven engines and those seeing occasional high-RPM use. The OEM-style design means no special pushrods, rocker geometry modifications, or head preparation beyond standard machining are required.

This valve is ideal for anyone rebuilding a SBC engine with original-specification cylinder heads, including Vortec platforms and traditional cast-iron blocks. Mechanics and engine shops choose FERREA valves for their consistency and repeatability across multiple engine builds. Installation pairs best with OEM-style or reproduction intake valves to maintain proper combustion chamber balance and ensure reliable cold starts and idle quality. Always verify head casting number and intake valve diameter before ordering to ensure correct application—SBC heads can vary, and matching intake and exhaust valve sizes is essential for proper sealing and performance.
