4. Check the condition of the capscrews and
lubricate the capscrew heads (underside),
threads and washers with clean engine oil.
Oil all cylinder head capscrew bosses, but
DO NOT oil threads in the cylinder block.
Do not install painted capscrews at locations that
are under the cylinder head cover.
5. Insert the short and long capscrews,
7-51/64 inches and 8-55/64 inches
(198.0 mm and 225.0 mm), in the respective
mounting holes. Tighten all cylinder head
capscrews finger-tight.
6. Check the alignment of the cylinder heads
by placing a straightedge against the
exhaust manifold mounting surfaces
(Figure 367). 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.
