Checking cylinder head for distortion
–  Use straight edge and feeler gauge to measure for distortion at several points.
l  Maximum permissible distortion: 0.1 mm.
  V15-0654
Cylinder head machining limit
–  Machining of the cylinder head (surface grinding) is only permissible down to the minimum dimension -a-.
l  Minimum dimension: -a- = 139.25 mm
