200 ENGINE ASSEMBLY Several of the head mounting capscrews have threaded holes drilled in the heads for bracketmounting purposes. The drilled capscrews must be located in the correct positions for proper bracket installation.
Do not install painted capscrews at locations that are under the valve cover.
There are two cylinder-head capscrew lengths: 198.0 mm and 225.0 mm.
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.
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.
Refer to Figure 6-59.
