IMPORTANT mounting information:
In order to optimize the self suction mode the valve bodies must be positioned correct ac-
cording to the water canals inside the cylinder head. The "leg" of the valve body must not be
placed in front of a canal. Fig 1 is showing the WRONG positioning and fig 2 is showing the
CORRECT positioning.
