Installation
Install the cylinder heads in the reverse order of removal:
• Always use new head gaskets.
• Cylinder heads and engine block surface must be
clean.
• Turn the crankshaft so that No. 1 piston is at TDC
(see page 6-19).
• Do not use the middle cover and lower cover for
storing removed items.
• Clean the middle cover and lower cover before
installation.
1. Install the front and rear exhaust manifolds to each
cylinder head, then tighten the self-locking nuts in a
crisscross pattern in two or three steps, beginning
with the inner nut.
• Apply oil to the self-locking nut threads.
• Always use new exhaust manifold gaskets.
2. Install the exhaust manifold covers.
