Remove the cylinder head assembly.
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 to identify the correct position.Note: Do not stamp the heads of the valves. Stamping or punching the heads of the valves could cause the valves to fracture.
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.
Ensure that the valve spring is compressed squarely or damage to the valve stem may occur.
