Cylinder Head
Both cylinder heads
1. NOTICE: The gasket sealing surfaces on the cylinder head and the cylinder block must be clean. Failure to follow these instructions may result in engine damage. For additional information, refer to Cylinder Head in the Removal.
NOTICE: The use of sealing aids (aviation cement, copper spray and glue) is not permitted. The gasket must be installed dry. Failure to follow these instructions may result in engine damage.
NOTICE: The new gasket has a film coating which is crucial to the ability of the gasket to seal correctly. Do not scratch the gasket.
NOTE: RH head gasket shown, LH head gasket similar.
Install the head gasket over the dowel pins.
2. NOTICE: Cylinder head machining or milling is not authorized by the Ford Motor Company. Cylinder head flatness must be within 0.0254 mm (0.001 in) across a 38.1 mm (1.5 in) square area. Failure to follow these instructions may result in engine damage.
NOTICE: The gasket sealing surfaces on the cylinder head and the cylinder block must be clean. Do not use metal scrapers, wire brushes, power abrasive discs or other abrasive means to clean the sealing surfaces. These tools cause scratches and gouges which make leak paths. Use a plastic scraping tool to remove all traces of old sealant.
NOTICE: The use of sealing aids (aviation cement, copper spray and glue) is not permitted. The gasket must be installed dry. Failure to follow these instructions may result in engine damage.
NOTICE: Do not allow the dowels to scratch the sealing surface of the cylinder head during cylinder head installation. Failure to follow these instructions may result in engine damage.
NOTE: LH shown, RH similar.
