Ford 351C C/6 1.650 Exhaust Valves

The Ford 351C C/6 1.650 Exhaust Valves from FERREA represent a premium upgrade for Ford Cleveland engine builders and performance enthusiasts seeking reliable, high-flow exhaust flow characteristics. Designed specifically for 351C and modified Cleveland platforms, this set of eight stainless steel exhaust valves delivers the durability and precision required for both street and competition applications. These valves are engineered to withstand elevated combustion temperatures and repeated thermal cycling without degradation.

Each valve features a 1.650-inch head diameter paired with an 11/32-inch valve stem and a 5.060-inch overall length, allowing efficient gas scavenging during the exhaust stroke while maintaining tight sealing under compression. The 6000 Series stainless construction resists oxidation and corrosion in high-heat environments, critical for maintaining valve integrity across extended operating ranges. FERREA's precision manufacturing ensures concentricity and dimensional consistency, reducing the likelihood of leakage and maximizing engine efficiency gains when paired with quality seat work and proper installation.

Engine builders, machine shops, and experienced enthusiasts rebuilding or upgrading Ford Cleveland engines will find this eight-valve set essential for comprehensive top-end restoration or performance enhancement. Installation requires professional valve seat cutting and proper clearance specification to ensure reliable operation. These valves are compatible with all 351C and Cleveland-based modified engines utilizing standard valve spacing and seat angles, making them a dependable choice for both original restorations and power-adder applications.
