to the threads and drive new studs to 25-40 lb ft torque (1.40 to 1.50 inch height).
Install Exhaust Manifold
Place a new gasket over the studs and against the cylinder head.
Position the exhaust manifold over the studs and hold it against the cylinder head.
Install the washers and nuts on the studs. If beveled (dished) washers are used, position them so
that the crown side faces the nut. On some engines, crabs are used in place of washers at the end positions
(Fig. 2). Beginning with one of the center stud nuts and working alternately toward each end of the manifold,
tighten the nuts to 30-35 lb ft torque.
If the engine is equipped with a mechanical automatic shutdown assembly, install the shutdown
valve adaptor and plug assembly in the exhaust manifold and secure it with two bolts and lockwashers.
