NOTE: Do not reuse cylinder head screws or gasket,
always replace with new parts.
NOTE: If crankshaft has not been turned since
installation of crank gear, turn it one (1) complete
revolution. This will set piston at top dead center
(TDC) of compression stroke, for proper valve
lash adjustment later.
1. Check to make sure there are no nicks or burrs on
sealing surfaces of cylinder head or crankcase.
2. Install a new cylinder head gasket with tab on gasket
in 4 o'clock position.
3. Install cylinder head and start six screws.
4. Using torque sequence shown, torque cylinder head
screws in two stages; initially to 24.4 N·m
(216 in. lb.), and fi nally to 42.7 N·m (378 in. lb.).

Install Rocker Arms and Push Rods

NOTE: Installation and seating of push rods into cam
lever recesses during this sequence is critical.
Position engine with cylinder head up if possible,
to aid with proper installation of push rods and
rocker arms, and adjusting valve lash.
NOTE: If being reused, push rods should always be
installed in their original position.
