Cylinder Head

Deck Flatness Inspection
If the warpage is less than 0.05 mm (0.002 inch), the cylinder head deck surface does not require resurfacing.
If the warpage is between 0.05 - 0.20 mm (0.002 - 0.008 inch) or any imperfections or scratches that could inhibit proper cylinder head gasket sealing are present, the cylinder head deck surface requires resurfacing.
If resurfacing is required the maximum amount that can be removed is 0.25 mm (0.010 inch).
If the cylinder head deck surface requires more than 0.25 mm (0.010 inch) material removal the head must be replaced.
