MACHINING CYLINDER HEAD MATING SURFACE - Cylinder Head Disassembled -
When machining cylinder head mating surface,
not more than 0.3 mm (0.012´´) may be taken
from total cylinder head thickness A = 129±0.1 mm
(5.078±0.004´´).
After machining a cylinder head either a gasket
of original thickness or one 0.3 mm (0.012´´)
thicker can be installed (also refer to 12 11 101).


* See Specifications

This requires machining of upper timing case
cover accordingly.
