EXHAUST HEADERS: Any header or manifold designed for
original equipment heads will fit the Edelbrock Street Cylinder
Heads. Exhaust ports are CNC profiled to match Fel-Pro #1411
exhaust gaskets which are recommended for this application.
SPARK PLUGS: Use 14mm x 3/4" reach gasketed spark plugs.
Heat range will vary by application and may range from
Champion N-9Y to N-14Y (or equivalent). If required for header
clearance, use Champion RC-12YC or equivalent which are 1/4"
shorter than "N" series plugs. Use anti-seize on the plug
threads to prevent galling in the cylinder head, and
torque to 10 ft./lbs. Do not overtighten sparkplugs!

INSTALLATION:
equipment cylinder heads. Consult service manual for specific
procedures, if necessary. For 454 and smaller Mark IV engines,
use Fel-Pro head gasket #1017-1 or equivalent. For 454 Mark
V engines, use Fel-Pro head gasket #1037 or equivalent. For
502 c.i.d. Mark V engines, use Fel-Pro head gasket #1047 or
equivalent. 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
).
