200 ENGINE ASSEMBLY
Page 6-53
Several of the head mounting capscrews have
threaded holes drilled in the heads for bracket-
mounting purposes. The drilled capscrews must
be located in the correct positions for proper
bracket installation.
There are two cylinder-head capscrew lengths:
198.0 mm and 225.0 mm.
4. Check the condition of the capscrews,
lubricate the capscrew heads (underside),
threads and washers with clean engine oil,
and insert the capscrews in the mounting
holes. Tighten all cylinder head capscrews
finger tight.
Do not install painted capscrews at locations that
are under the valve cover.
Refer to Figure 6-59.
5. Check the alignment of the cylinder heads
by placing a straightedge against the
exhaust manifold mounting surfaces. Using
a feeler gauge, measure any gaps between
the straightedge and manifold mounting
surfaces. The heads should be in alignment
within 0.005 inch (0.127 mm). If not,
reposition the heads to achieve the specified
alignment.
