Intake Valve

The Ford Small Block intake valve (M-6507-A304) is a critical engine component engineered for high-reliability operation in Ford fuel and naturally aspirated powerplants. This intake valve is designed for operators and technicians who demand OEM-equivalent durability and precise fit in small-block Ford engines. Whether you're rebuilding a 289, 302, or 351W platform, this valve ensures proper air-fuel charge delivery and repeatable combustion cycles—essential for both street and off-road performance applications.

Constructed from durable stainless steel, this intake valve features a 2.020-inch head diameter, 11/32-inch valve stem, and 5.340-inch overall length—specifications that match Ford's exacting tolerances for proper seating and thermal cycling resistance. The stainless-steel construction resists corrosion and maintains valve-head integrity under sustained combustion temperatures, while the precision-ground stem ensures consistent clearance with valve guides. At 0.35 lbs, the valve's weight is optimized to minimize inertial stress on rocker arms and pushrods during high-RPM operation, reducing mechanical wear and extending component life.

This intake valve is essential for engine overhaul, restoration, or performance rebuild scenarios where OEM replacement parts are non-negotiable. Installation requires proper valve-seat machining and clearance verification by qualified technicians to ensure leak-free sealing and correct pushrod geometry. Compatible exclusively with Ford Small Block platforms, this valve must be paired with matching exhaust valves, springs, and related top-end components to achieve balanced engine performance and reliability.
