SBC C/6 1.940in Intake Valves

The FERREA SBC C/6 1.940in Intake Valves are premium small-block Chevy cylinder head components engineered for precision engine builders, performance shops, and serious weekend warriors who demand valve reliability under sustained RPM loads. This set of eight stainless steel intake valves delivers the dimensional consistency and material integrity required for high-revving naturally aspirated and forced-induction builds where margin for error is zero.

Each valve measures 1.940 inches across the head with an 11/32-inch valve stem and extends 4.960 inches in overall length—specifications that directly impact flow characteristics, seating pressure, and thermal conductivity in the combustion chamber. Stainless construction provides corrosion resistance and superior heat dissipation compared to carbon steel alternatives, critical when operating at extended throttle or in high-ambient conditions. The 6000 series designation indicates this valve is optimized for small-block Chevy applications where factory head geometry and port velocity demand exacting tolerances.

Buyers assembling or rebuilding small-block Chevy engines—whether for street performance, vintage racing, or marine duty—rely on FERREA's intake valve specifications to match OEM head pocket dimensions while maintaining the dimensional accuracy that prevents valve recession and seat wear. Eight valves per set covers a complete small-block Chevy intake-side requirement, eliminating the need to source components from multiple suppliers.

FERREA valves are recognized across the performance engine-building community for material quality and dimensional consistency. When precision and durability matter in a time-critical rebuild or a high-output engine program, these intake valves deliver the foundation every cylinder head depends on.
