– Using a 55° stone for the intake and an 80°

stone for the exhaust valve, reduce the valve
seat contact width to the appropriate value
mentioned above.

– Finally, coat the valve head sealing seating sur-

face with a fine paste of valve grinding com-
pound using a manual valve grinding mandrel.
Lightly grind the valves until a smooth, even,
uniform sealing surface of the appropriate in-
side and outside diameter is obtained on both
the valve and the seat. Use only a hand held
valve grinding mandrel with a suction cup, rotat-
ing the valve back and forth through about 45°,
and then advancing the valve 45° before repeat-
ing this operation.

Installation

For installation, reverse the removal procedure.
Pay attention to the following details.
