Exhaust Valve - 1.600 (1)

The Edelbrock Exhaust Valve – 1.600 in Head with 11/32 in Valve Stem is a precision stainless steel component engineered for small block Mopar high-performance engines. Part of Edelbrock's renowned Performer RPM lineup, this exhaust valve delivers optimized flow characteristics and durability for engine builders and enthusiasts seeking reliable valve components that support consistent combustion efficiency.

The 1.600-inch head diameter is sized specifically to match Performer RPM cylinder head porting specifications, ensuring proper sealing and airflow optimization without modification. Stainless steel construction provides superior corrosion resistance and thermal stability compared to standard valve materials, critical for high-RPM applications where exhaust gas temperatures and pressure cycling demand long-term reliability. The 11/32-inch valve stem diameter is the industry standard for small block Mopar applications, guaranteeing direct compatibility with OEM and performance valve guides and seats.

This valve suits engine builders, machine shops, and performance enthusiasts restoring or upgrading small block Mopar powerplants—whether for street performance, bracket racing, or classic car applications. Edelbrock's Performer RPM valve package is designed to work seamlessly with matched intake valves and cylinder head components, delivering consistent performance across the RPM band. Each valve ships individually and must be paired with a complete valve train assembly during installation.

When sourcing OEM or performance valve components for small block Mopar engines, valve size and material directly impact combustion efficiency, exhaust scavenging, and durability under load. Stainless steel valves resist oxidation and maintain precise sealing surfaces longer than ferrous alternatives, reducing the frequency of valve recession and seat erosion—particularly important in high-heat, high-boost environments.
