The JE Pro Seal head gasket for Ford Cosworth DOHC YB and related heads fits a 93.5 mm bore and uses a 0.051 inch thickness to match thicker gasket requirements. Offered as a direct-fit replacement, it is suitable for rebuilds and repairs where a larger gasket thickness is needed to restore proper head-to-block sealing for Cosworth-family applications.
