SBF H/P 1.940in Intake Valve

The FERREA SBF H/P 1.940in Intake Valve (Part F5059-1) is a precision-engineered intake valve engineered for Small Block Ford engine builds requiring OEM-specification or performance-level component reliability. This 1.940-inch head diameter valve features a 11/32-inch valve stem and measures 5.075 inches in total length, designed to meet exact factory tolerances for direct bolt-in installation. Constructed from stainless steel, the valve resists corrosion and thermal degradation under sustained engine operating temperatures, making it suitable for street engines, daily-driven vehicles, and entry-level performance builds.

FERREA's 5000 Series valves represent mid-level component quality within the Small Block Ford aftermarket. The 1.940-inch intake valve head size matches factory dimensions, ensuring compatibility with stock or lightly-ported cylinder heads without modification. Stainless steel construction provides superior oxidation resistance compared to chrome-molybdenum alternatives, particularly valuable in high-heat environments or vehicles stored outdoors. The 11/32-inch stem diameter maintains OEM valve guide specifications, eliminating the need for machine work on stock or quality replacement heads. Weight and dimensional consistency across the series supports balanced valve train dynamics and predictable combustion chamber behavior.

This intake valve addresses builders restoring original Small Block Ford specifications, users replacing worn factory components, and technicians assembling basic-to-intermediate performance engines where precision OEM-equivalent parts matter. The FERREA SBF valve is sold individually—complete five-valve sets require five units (one intake valve per cylinder on a five-valve head configuration, though most Small Block Fords use two intake and two exhaust per cylinder). Buyers sourcing intake valves for Small Block Ford rebuilds should verify cylinder head port design and valve guide condition before installation to ensure proper seating and longevity.
