1. Clean gasket material, dirt and debris from cylinder heads. Wash cylinder heads with a suitable soap and water solution. Dry cylinder heads completely using compressed air.
2. If removed, install pipe plugs and alignment dowels to cylinder heads. Apply Pipe Sealant with Teflon(R) D8AZ-19554-A or equivalent meeting Ford specification WSK-M2G350-A2 to pipe plugs prior to installation. Tighten pipe plugs as follows:
- 1/4 inch pipe plug: 8-11 Nm (71-97 inch lbs.)
- 1 inch pipe plug: 71-86 Nm (53-63 ft. lbs.)
3. If removed, install valve guides into cylinder heads using Valve Guide Remover/Replacer. Lubricate valve guides and install by driving valve guides into cylinder heads from top of cylinder heads.

NOTE: Intake valve stem seals are gray in color and exhaust valve stem seals are black.





4. Using Valve Stem Seal Replacer T89P-6510-C, install valve stem seals onto cylinder head valve guides.
5. Lubricate valve stems and guides with Engine Assembly Lubricant D9AZ-19579-D or equivalent meeting Ford specification ESR-M99C80-A. Install valves into cylinder heads.

NOTE: Install valve springs with color end up.

6. Using Valve Spring Compressor Set T87C-6565-A, install valve springs, valve spring retainers and valve spring retainer keys onto cylinder head and valves.

NOTE: Make sure valve tappets and valve adjusting spacers are installed in their original locations.

7. Lubricate valve tappets and valve adjusting spacers with Engine Assembly Lubricant and install valve tappets to cylinder heads.
8. Install valve adjusting spacers to valve tappets with numbered side down.
