351 Ford High Output (H.O.) Cylinder Head Indicated by 3 raised ribs on the end of the head. 2 raised ribs indicates a standard 351, 250HP with hardened exhaust seats. A flat head, with no raised ribs, indicates a older style without hardened seats, requiring Valve Tech or a lead substitute. Flat Head and 2-rib heads are compatible, just make sure both take 14mm plugs. |
