Place a small amount of fine valve grinding paste evenly around the contact face of the valve.
Place the valve in position and, using a suitable valve grinding tool, rotate the valve back and forth a few degrees on its seat, using light pressure.
Raise the valve frequently during lapping and turn it into a new position after a few laps or rotations.
Lap only until a continuous but narrow lapping mark is visible on both the valve seat and valve face.
Thoroughly clean all surfaces to remove traces of valve grinding paste from the cylinder head, valve seat and valve face.
Repeat steps 5 to 8 for the remaining valves.
