Ford 302/351 Valve Angle Diagram - 35°/45°/55° Cut, 2.2255 in. Intake Valve

This document is a single technical illustration showing a cross-section diagram of an engine valve, labeled "302-351" (indicating applicability to Ford 302 and 351 cubic-inch engines). The diagram depicts the valve head in profile with three angle callouts on the valve face/margin area: 35°, 45°, and 55°, arranged from the upper face toward the outer edge. A callout indicates a seating/contact band that is 0.070 inches wide. The overall valve head diameter is dimensioned across the bottom of the drawing as 2.2255 inches nominal. From this diagram a reader can learn the multi-angle valve face/seat geometry (35°/45°/55°) used when grinding or machining valves and seats for these engines, the specified width of the 0.070-inch contact band, and the nominal 2.2255-inch head diameter, which corresponds to an intake valve size. The image appears to be reproduced from a factory or aftermarket engine service manual and was uploaded as part of an album of Ford engine reference pages (head gaskets, distributor specs, firing orders, service specifications) for a 1972 Ford Ranchero.
