Refer to Figure 366.
1. Place the head gaskets in position on the
locating pins in the cylinder block deck.
2. Place a fire ring carefully in position on top of
each cylinder sleeve.
Check that the design of the fire rings used is the
correct match for the cylinder sleeves installed.
3. Place the partially assembled cylinder heads
(valves, nozzle holder sleeves, core/pipe
plugs installed) in position over the guide
pins on the cylinder block.
Two of the head mounting capscrews have
threaded holes drilled in the heads for
bracket-mounting purposes. The drilled
