Note:
- If the oil clearance between the camshaft and brackets (see above) more than allowed, the cylinder head must not be reground.
- If the oil clearance between the camshaft and brackets is within tolerance, check the cylinder head for distortion.
- If warpage is less than 0.05 mm, regrinding of the cylinder head is not required.
- If warping is between 0.05 and 0.2 mm, regrind the cylinder head.
- The maximum thickness of the metal removed during regrinding is 0.2 mm with a head height of 93 mm.
