SBC C/6 1.940in Intake Valves

The FERREA SBC C/6 1.940in Intake Valves are precision-engineered components designed for small-block Chevrolet engines, targeting performance enthusiasts and serious engine builders. These intake valves are essential upgrades for any SBC project seeking improved cylinder head flow characteristics and reliable valve sealing at higher RPMs. Whether you're building a street performance engine, preparing for track duty, or restoring a classic muscle car, quality intake valves directly impact combustion efficiency, power delivery, and overall engine longevity.

FERREA has earned its reputation among professional engine builders by delivering consistent metallurgy and exacting tolerances that eliminate common valve failures under sustained boost or aggressive cam profiles. The 1.940-inch head diameter represents the optimal flow size for most street and mild performance small-block applications, balancing flow capacity with reliable sealing and durability. FERREA intake valves are manufactured from premium stainless steel alloys that withstand thermal cycling and resist corrosion from fuel additives and combustion byproducts.

The C/6 designation indicates this valve series features chromium plating on the valve stem, reducing friction during operation and extending the working life of both the valve and valve guide. Precision grinding of the valve face and seat contact area ensures consistent sealing pressures across the entire rev range, eliminating marginal leakage that can plague performance engines. These valves are ideal for those looking to enhance their engine's performance and reliability.
