SBC 1.625 C/P Exhaust Valves 5/16 5.010 OAL

The SBC 1.625 C/P Exhaust Valves 5/16 5.010 OAL from FERREA are purpose-built components for small-block Chevrolet cylinder head modifications and high-performance engine builds. These exhaust valves are engineered for serious enthusiasts and professional engine builders who demand precision metallurgy and exact dimensional tolerances in their valve train assemblies. Whether you're assembling a streetable performance engine, preparing for competition, or restoring a classic SBC platform, these valves deliver the reliability and durability required for sustained operation under demanding conditions.

FERREA exhaust valves are manufactured from premium alloy steel formulations specifically selected to withstand thermal cycling and combustion pressures inherent to modern ignition systems and forced induction applications. The 1.625-inch head diameter provides optimal flow characteristics for small-block Chevrolet heads, while the 5/16-inch stem diameter ensures compatibility with standard valve guides and rocker arm geometry. The 5.010-inch overall length is precisely engineered to work seamlessly with your existing valve spring assemblies, pushrods, and rocker configurations without requiring additional machine work or spacer adjustments.

These valves are ideal for SBC enthusiasts upgrading stock exhaust valve packages to premium performance specifications, particularly in applications involving camshaft upgrades, cylinder head work, or higher-RPM operation. Installation requires basic machine shop competency—proper valve seating, spring seat verification, and rocker arm clearance checks are essential to ensure correct operation. The compact 2.25 lb shipping weight reflects the precision engineering of each individual valve, and the standard 5/16-inch stem compatibility makes these valves a direct upgrade path for countless small-block platforms from entry-level street engines to serious race applications.
