NOTE

The cylinder head must be cool before removing it from the engine. Cylinder head warpage can result if a warm or hot cylinder head is removed.

NOTE

Place clean shop towels over exposed engine cavities. Carefully remove the towels so foreign material is not dropped into the engine.

NOTE

The cylinder head bolts must be discarded and new bolts must be installed. They are a tighten-to-yield design and cannot be reused.

NOTE

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 that make leak paths. Use a plastic scraping tool to remove all traces of the head gasket.

NOTE

Aluminum surfaces are soft and can be scratched easily. Never place the cylinder head gasket surface, unprotected, on a bench surface.

1. Remove the 10 bolts and the cylinder head. Discard the bolts. Remove and discard the cylinder head gaskets.
   
   NOTE

   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 that make leak paths. Use a plastic scraping tool to remove all traces of the head gasket.
   
   
   
   NOTE

   Observe all warnings or cautions and follow all application directions contained on the packaging of the silicone gasket remover and the metal surface prep.
   
   
   
   NOTE

   If there is no residual gasket material present, metal surface prep can be used to clean and prepare the surfaces.
   
   
   
   
   

   

   Fig. Removing the cylinder head (LH shown, RH similar)
2. Clean the cylinder head-to-cylinder block mating surfaces of both the cylinder head and the cylinder block in the following sequence.
   1. Remove any large deposits of silicone or gasket material with a plastic scraper.
   2. Apply silicone gasket remover, following package directions and allow to set for several minutes.
   3. Remove the silicone gasket remover with a plastic scraper. A second application of silicone gasket remover may be required if residual traces of silicone or gasket material remain.
   4. Apply metal surface prep, following package directions, to remove any remaining traces of oil or coolant and to prepare the surfaces to bond with the new gasket. Do not attempt to make the metal shiny. Some staining of the metal surfaces is normal.
3. Support the cylinder heads on a bench with the head gasket side up. Check the cylinder head distortion and the cylinder block distortion, paying particular attention to the oil pressure feed area.

To install:

1. Install the head gasket over the dowel pins.
   
   NOTE

   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.
   
   
   
   NOTE

   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.
   
   
   
   NOTE

   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.
   
   
   
   NOTE

   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.
