The World Products Ford I-051 (often referenced with 1-051, 1-061, or as a "Windsor") is a discontinued early 1990s cast-iron cylinder head for small-block Fords featuring 200cc intake ports, 64cc combustion chambers, and 2.02"/1.60" valves. Designed for performance, they share 20-degree stock valve angles and stock port locations, making them compatible with standard intakes and headers.
