All cylinder heads 

CAUTION: The cylinder head must be cool before removing it from the engine. Cylinder head warpage may result if a warm or hot cylinder head is removed.
CAUTION: Place clean shop towels over exposed engine cavities. Carefully remove the towels so foreign material is not dropped into the engine.
CAUTION: The cylinder head bolts must be discarded and new bolts must be installed. They are a tighten-to-yield design and cannot be reused.
CAUTION: 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. Failure to follow this procedure may cause future oil leakage.
CAUTION: Aluminum surfaces are soft and can be scratched easily. Never place the cylinder head gasket surface, unprotected, on a bench surface.
NOTE: RH shown, LH similar.
67. Remove the bolts and the cylinder head.
    • Discard the cylinder head gasket.
    • Discard the cylinder head bolts.
Fig 59: Cylinder Head Bolts

CAUTION: 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. Failure to follow this procedure may cause future oil leakage.
CAUTION: Observe all warnings or cautions and follow all application directions contained on the packaging of the Silicone Gasket Remover and the Motorcraft Metal Surface Prep.
NOTE: If there is no residual gasket material present, Motorcraft Metal Surface Prep can be used to clean and prepare the surfaces.
68. Clean the cylinder head-to-cylinder block mating surfaces of both the cylinder head and the cylinder block.
    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 Motorcraft 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.
NOTE: Make sure all cylinder head surfaces are clear of any gasket material, RTV, oil and coolant. The cylinder head surface must be clean and dry before running a flatness check.
NOTE: Use a straightedge that is calibrated by the manufacturer to be flat within 0.005 mm (0.0002 in) per running foot length, such as Snap-On® GA438A or equivalent. For example, if the straightedge is 61 cm (24 in) long, the machined edge must be flat within 0.010 mm (0.0004 in) from end to end.
NOTE: LH shown, RH similar.
69. Support the cylinder head on a bench with the head gasket side up. Inspect all areas of the deck face with a straightedge, paying particular attention to the oil pressure feed area. The cylinder head must not have depressions deeper than 0.0254 mm (0.001 in) across a 38.1 mm (1.5 in) square area or scratches longer than 0.0254 mm (0.001 in).
