SBC P/F 1.600in Exhaust Valve

The SBC P/F 1.600in Exhaust Valve from Manley is designed for serious small-block Chevrolet engine builders and performance enthusiasts. This exhaust valve is ideal for applications ranging from street machines to high-revving drag platforms, providing the reliability and durability needed for sustained high-RPM operation.

Manufactured from premium alloy steel, this exhaust valve is engineered to withstand extreme thermal cycling and combustion pressures typical in performance applications. The precision-ground stem and head ensure concentricity, which is critical for proper seating, reducing leak-down, and maximizing scavenging efficiency during the exhaust stroke.

Builders restoring classic Chevrolets or tuning modern crate engines will find that upgrading to Manley's valvetrain components not only extends engine life but also unlocks reliable power gains. The 1.600-inch head diameter is specifically sized for optimal flow characteristics in small-block Chevrolet cylinder heads, making it a trusted choice for performance upgrades.
