INSTALLATION:
Installation is the same as for original equipment
cylinder heads. Consult service manual for specific procedures, if
necessary. For 454 and smaller Mark IV engines, use Edelbrock head
gasket #7302, Fel-Pro head gasket #1017-1 or equivalent. For 454
Gen V engines, use Fel-Pro head gasket #1037, or equivalent. For 502
c.i.d. Gen V engines, use Fel-Pro head gasket #1047 or equivalent.
NOTE:
For 454 and smaller Mark IV engines, Edelbrock Cylinder Head
Gasket Set #7362 may be used.
The set contains all gaskets
necessary to install these cylinder heads onto a Mark IV engine,
including intake, exhaust, cylinder head, distributor, water neck, and
valve cover gaskets.
Figure 1
Be sure that the surface of the block and the surface of the head is
thoroughly cleaned to remove any oily film before installation. Use
alcohol or lacquer thinner on a lint-free rag to clean. Apply liquid teflon
or suitable thread sealer to head bolt threads. Torque short bolts to 65
ft./lbs. and long ones to 75 ft./lbs. in three steps following the factory
tightening sequence (see Figure 1). A re-torque is recommended after
initial start-up and cool-down (allow 2-3 hours for adequate cooling.
