Remove the cylinder head. Refer to Disassembly and Assembly, "Cylinder Head - Remove".
Keep all parts clean from contaminants.Contaminants may cause rapid wear and shortened component life.
Note: Note the location and orientation of all components for assembly purposes.
Clean the bottom face of the cylinder head. Check the depth of the valves below the face of the cylinder head before the valve springs are removed. Refer to Specifications, "Cylinder Head Valves" for the correct dimensions.
Place a temporary identification mark on the heads of the valves in order to identify the correct position.

Personal injury can result from being struck by parts propelled by a released spring force.Make sure to wear all necessary protective equipment.Follow the recommended procedure and use all recommended tooling to release the spring force.
Install Tooling (B) on cylinder head (1) in order to compress valve spring (5) .
Ensure that the valve spring is compressed squarely or damage to the valve stem may occur.
Apply sufficient pressure to Tooling (B) in order to remove valve keepers (3). Do not compress the spring so that valve spring retainer (4) touches valve stem seal (6) .
Slowly release the pressure on Tooling (B) .
Remove valve spring retainer (4). Remove valve spring (5). Remove valve (2) .
Use Tooling (C) in order to remove valve stem seal (6) .
Repeat Steps 4 through 7 for the remaining valves.Installation Procedure

Keep all parts clean from contaminants.Contaminants may cause rapid wear and shortened component life.
Clean all components of the cylinder head assembly. Ensure that all ports, all coolant passages and all lubrication passages in the cylinder head are free from debris. Follow Steps 1.a through 1.d in order to inspect the components of the cylinder head assembly. Replace any components that are worn or damaged.
Inspect the cylinder head for wear and for damage. Refer to Testing and Adjusting, "Cylinder Head Inspect".
Inspect the valve seats for wear and for damage. Refer to Specifications, "Cylinder Head Valves" for further information.
Inspect the valve guides for wear and for damage. Refer to Specifications, "Cylinder Head Valves" and Testing and Adjusting, "Valve Guide - Inspect" for further information.
Inspect the valves for wear and for damage. Refer to Specifications, "Cylinder Head Valves ".
Inspect valve springs (5) for damage and for the correct length. Refer to Specifications, "Cylinder Head Valves ".
