Reassembly of the cylinder heads
1. Coat the valve Stems with engine oil, then insert
them into the valve guides.
2. Install the valve springs and rotators to the valve
guides. Compress each valve spring with the
Valve spring pusher, then install the valve cotters
on the valve Stem.
3. Lightly tap on the top of each valve stem with a
soft-faced mallet to make sure that the valve
spring and cotters are properly installed.
Install cylinder head assemblies
IMPORTANT! Before you install the cylinder
head assembly, measure the protrusion of each
piston. Make sure that the protrusion is correct.
1. Install the exhaust connector to the cylinder
head, while pushing down the exhaust connector
so it touches the edge of the bolt hole.
NOTE! Place the gasket so its "MANIFOLD" printed
side aligns with the connector side.
2. Install the Eye nut to the stud bolt, and lift up the
cylinder head assembly. Locate the head aligning
its holes with the dowel pins, and keep the head
being slightly separated from the cylinder. Apply
engine oil to the threads and bearing surfaces of
head bolts, then wipe off the excessive oil before
tightening.
3. Tighten the cylinder head bolts with the specified
torque in the order shown in the drawing.
