9. INSPECT CYLINDER HEAD FOR FLATNESS
(a) Using a precision straight edge and feeler gauge, mea-
sure the warpage on the surfaces which contacts the cyl-
inder block and manifolds.
Maximum warpage:
0.05 mm (0.0020 in.) for cylinder block surface
0.10 mm (0.0039 in.) for intake manifold surface
0.10 mm (0.0039 in.) for exhaust manifold surface
If the warpage is greater than maximum, replace the cylinder
head.
10. INSPECT CYLINDER HEAD FOR CRACKS
(a) Using a dye penetrate, check the combustion chamber,
intake ports, exhaust ports and cylinder block surface for
cracks.
If cracked, replace the cylinder head.

Standard overall length: 95.45 mm (3.7579 in.)
Minimum overall length: 94.95 mm (3.7382 in.)
If the overall length is less than minimum, replace the valve.
(b) Using a micrometer, measure the diameter of the valve
stem.
Valve stem diameter:
5.470 to 5.485 mm (0.2154 to 0.2159 in.)
