Engine Preparation and
Component Removal
1. Assemble studs to exhaust manifold and position
all gaskets as shown between risers. Refer to “In-
stallation Diagrams” at the end of this section.
IMPORTANT: Restrictor gaskets or manifold sep-
arator gaskets must be installed in order shown.
!
CAUTION
If engine is equipped with closed cooling, MAN-
IFOLD SEPARATOR GASKET MUST BE IN-
STALLED ONLY ON EXHAUST MANIFOLD. Fail-
ure to install separator gaskets on exhaust
manifolds, or to install in a location other than
shown, will result in severe engine damage.
2. Install elbow on riser(s) and studs. Attach using
nuts and washers.
NOTE: Drain plugs in risers must be positioned fac-
ing flywheel end of engine, unless otherwise noted.
3. Torque all fasteners, in a diagonal pattern, to 27
lb. ft. (37 N·m).
4. Place spacers between riser plate, if so
equipped, and fasten with existing nuts. Tighten
securely.
5. Reattach and tighten securely all parts previously
removed from elbow to appropriate position on
riser bracket, if so equipped.
IMPORTANT: On elbows with ignition amplifier,
be sure to reconnect amplifier and wiring har-
ness ground wires to one of the attaching screws
and that amplifier spacers are installed between
amplifier and exhaust elbow. Tighten screws se-
curely.
IMPORTANT: On elbows with shift plate (MCM
