SBC H/P 1.940in Intake Valves

The FERREA SBC H/P 1.940in Intake Valves (Part Number F5101-8) are premium performance intake valves engineered for Small Block Chevy engines requiring high-flow cylinder head work. This set of eight stainless steel valves delivers the precision valve control essential for race-prepped and street performance builds where reliable airflow management directly impacts horsepower and throttle response. FERREA's 5000 Series represents the upper tier of their valve lineup, designed for builders who demand consistent performance across sustained high-RPM operation.

Each valve features a 1.940-inch head diameter paired with an 11/32-inch valve stem and 4.935-inch overall length—specifications that match OEM and aftermarket SBC cylinder head port requirements. The stainless steel construction resists thermal fatigue and corrosion, critical in high-heat engine compartments and extended dyno sessions. These dimensions ensure proper seating geometry and flow characteristics in port-matched heads, eliminating flow restrictions at the intake tract entrance where cylinder filling efficiency begins. The eight-piece configuration covers a complete set for a small block engine, simplifying sourcing and ensuring uniform valve performance across all cylinders.

FERREA intake valves are standard equipment in competition and high-output street builds where factory valve material and geometry cannot withstand sustained boost, nitrous, or high-compression loads. This product is suited for engine builders, machine shops, and performance enthusiasts restoring or upgrading Small Block Chevy platforms—from classic muscle car restorations to modern bracket racing and road course platforms. The 5000 Series intake valve set provides the durability and flow consistency required when precision engine work demands components that will not become a performance or reliability bottleneck.
