The MANLEY SBC B/P 1.940in Intake Valve (MPN 10576-1) is a precision-engineered stainless steel intake valve designed for small block Chevy and Ford engine builders who demand reliability without premium pricing. This Budget Series valve delivers OEM-equivalent flow characteristics and thermal stability, making it a practical choice for street engines, weekend warriors, and budget-conscious restoration projects where intake valve quality directly impacts combustion efficiency and longevity.
The valve features a 1.940-inch head diameter paired with a 0.342-inch valve stem, optimized for small block applications where seat pressure and flow velocity directly influence cylinder scavenging. At 4.911 inches long, it integrates seamlessly with standard rocker geometries and pushrod configurations. Stainless steel construction resists corrosion and oxidation under sustained combustion temperatures, a critical advantage in engines subject to varying maintenance intervals or storage in humid environments. The valve's symmetrical head profile and precision-ground seat angle ensure repeatable sealing and predictable valve float characteristics across the RPM band.
This intake valve serves engine builders restoring or refreshing small block Chevy and Ford platforms—from carbureted daily drivers to light-duty performance builds. It is equally suited for machine shops sourcing complete valve sets and for technicians who need individual replacements without stepping up to high-dollar titanium or hardened-stem options. The MANLEY reputation for dimensional consistency means minimal machine work on ports or valve seats, reducing overall machine costs while maintaining thermal and flow integrity.
Sold individually, this valve must be paired with matching exhaust valves and a full valve train (springs, retainers, locks, keepers) to complete an engine build. Verify your specific engine block, year, and induction type before purchasing to ensure compatibility with your cylinder head and valve seat configuration.
