ASSEMBLY

WARNING: EYE PROTECTION IS REQUIRED DURING USE OF COMPRESSED AIR. FAILURE TO WEAR EYE PROTECTION COULD RESULT IN PERSONAL INJURY.

CAUTION: The cylinder head surface finish is measured in microns. For proper head gasket sealing, avoid any contact of finish with metallic objects.

1. Clean gasket material, dirt and debris from cylinder heads. Wash with a suitable soap and water solution and dry completely using compressed air if pipe plugs have been removed.
- If gasket material remains on the cylinder head after cleaning, use a plastic tipped scraper to remove remaining material.

2. Install the pipe plugs and alignment dowels to cylinder heads, if removed.
- Apply pipe sealant to plugs prior to installation. Use Sealer or equivalent meeting Ford specification SM-4G-4644-AA/AB.






3. Use a Valve Guide Remover/Replacer and install the valve guides, if removed.





4. Use a Valve Stem Seal Replacer and install the valve stem seals onto the valve guides.





5. Install the valves into the cylinder heads.
- Lubricate valve stems and guides before assembly. Use API, SO SAE 50 Assembly Fluid or equivalent meeting Ford specification WSE-M2C908-A.
