c - Seat width: 2.4 mm (0.094 in.)
30 - Upper correction angle 45 - Valve seat angleZ - Bottom surface of cylinder head- Insert valve into guide and press firmly against valve seat.
The maximum permissible refacing dimension is the difference between
the actual distance measured at the cylinder head and the specified
