INSTALLATION
Installation is the same as for original equipment cylinder heads.
Consult service manual for specific procedures, if necessary. For 389-
455 engines, use Edelbrock #7381, Fel-Pro #1016 or equivalent head
gaskets. NOTE: Edelbrock Cylinder Head Gasket Set #7382 may also
be used. This gasket set includes all necessary gaskets for cylinder
head installation, including cylinder head, intake, exhaust, waterneck
and valve cover gaskets. Be sure that the surface of the block and the
surface of the head are thoroughly cleaned to remove any oily film

Note: Torque upper row of bolts to 105 ft./lbs., torque lower row of bolts to 95 ft./lbs. in three even
increments. Coat threads, washers, and underside of bolt heads with motor oil for accurate torque
readings. Start in center and work out towards ends following numbered sequence. Re-torque all head
bolts after initial warm-up and cool-down.
PONTIAC CYLINDER HEAD INTAKE MANIFOLD
GASKET FITTING:
NOTE 1: The position of the intake port entry on all Edelbrock Pontiac cylinder heads has the same roof height as a Pontiac 455 Super Duty cylinder
head. This was done to provide the best performing intake port while maintaining a stock Pontiac port location. The Fel-Pro 1233 intake manifold
gasket has a port roof to intake manifold bolt hole centerline dimension that is .06" lower than 455 Super Duty head dimension. When installing the
Fel-Pro 1233 intake gasket on Edelbrock Pontiac cylinder heads, align the gasket with the intake port entries. Three of the bolt holes in the gasket will
have to be elongated as shown in the illustration.
NOTE 2: The radii of the intake port entry corners on Edelbrock Pontiac cylinder heads is 3/16" to maximize the cross-sectional area through smallest
part of the port. The corners of the intake port openings of a Fel-Pro 1233 intake manifold gasket are 3/8". If you are using the intake manifold without
port-matching the runner exits or if you port match to the 3/8" radius, you do not have to modify the corners of the port openings in the gasket. If you
are port-matching to the 3/16" radii in the cylinder head, then the corners of the gasket port opening should be modified.

before installation. Use alcohol or lacquer thinner on a lint-free rag to
clean. Coat threads, washers, and underside of bolt heads with motor
oil for accurate torque readings. Torque upper row of bolts to 105
ft./lbs., torque lower row of bolts to 95 ft./lbs. in three even increments
(see Fig. 1). Start in center and work out towards ends. A re-torque is
recommended after initial start-up and cool-down (allow 2-3 hours for
adequate cooling).
