SBC C/6 1.940 Intake Valves

The SBC C/6 1.940 Intake Valves from Ferrea are precision-engineered components designed for small-block Chevrolet engines undergoing serious performance modifications. Built for enthusiasts and mechanics who demand reliability in high-RPM applications, these intake valves deliver the durability needed in competition engines, street builds, and extensively modified powerplants.

Ferrea's intake valves are manufactured to exacting tolerances using premium alloys engineered to withstand elevated combustion pressures and extended valve-train stress. The 1.940-inch head diameter is optimized for SBC C/6 cylinder heads, providing excellent flow characteristics while maintaining structural integrity under aggressive cam profiles and high-lift applications. The precise engineering ensures minimal flutter and consistent seating, critical factors in maintaining compression and preventing blowby in high-performance engines.

These valves integrate seamlessly with compatible valve seats and springs, forming a complete valve-train system that resists thermal fatigue and mechanical wear. These intake valves are essential for any SBC C/6 head rebuild targeting sustained performance or racing duty. Mechanics and engine builders routinely specify Ferrea valves for their reputation in endurance testing and proven reliability.
