Although Edelbrock Cylinder Heads will accept OEM components (valve covers, intake manifold, etc.), we highly recommend that
premium quality hardware be used with your new heads.
HEAD BOLTS or STUDS: High quality head studs or head
bolts with hardened washers must be used to prevent
galling of the aluminum bolt bosses. Edelbrock Head Bolt Kit
#8555 includes two longer-than-stock bolts which must be
used with these cylinder heads. If you use any other head
bolts, you must use the two head bolts and washers supplied
with these heads in position #5 in Fig. 1. This position will
not accept stock length head bolts.
ROCKER ARMS AND VALVE TRAIN: Adjustable rocker
arms must be used with cams having greater than stock
valve lift. We recommend original equipment or aftermarket
adjustable rocker arm assemblies, along with matching
pushrods (stock length, 7.375").
NOTE: These heads are designed to accommodate stock
stamped steel rocker arm assemblies, and stock-like
aftermarket setups. Ductile iron adjustable arms may require
special clearancing of the rocker arm body in order to clear
valve spring retainers. Also, non-stock spec, aftermarket
rocker arms may require special modifications.
CAUTION: Before installing rocker shafts, check for burrs or
other obstructions on the machined saddles where the shaft
sits. Remove any burrs and clean saddles thoroughly, if
necessary.
INTAKE MANIFOLD: Although stock intake manifolds will fit,
Edelbrock Performer RPM Chrysler Cylinder Heads are
matched in size and operating range with Edelbrock Performer
RPM intake manifold #7176. Edelbrock #7276 or Fel-Pro
intake manifold gaskets #1213 are recommended. Apply
Gasga-cinch Edelbrock #9300 to intake surface of heads and
position intake gaskets. Do not use cork or rubber end seals
supplied with gaskets. Set the manifold on the engine with
gaskets installed and measure the gap between the block and
the manifold end seal surface. Be sure to remove any dowel
pins which may have used with the stock intake manifold.
Remove the manifold and apply enough automotive RTV
Silicone sealer to fill the gap along front and rear of block,
overlapping gaskets at the four corners. Install manifold and
torque manifold bolts to 25 ft./lbs.

ACCESSORIES
VALVE COVERS: Edelbrock Performer RPM heads accept
stock or aftermarket valve covers. Edelbrock offers valve
covers #4495 & #4295, along with gasket set # 7592 for this
particular application.
EXHAUST HEADERS: Any header or manifold designed for
original equipment heads will fit Edelbrock Performer RPM
Chrysler Cylinder Heads. Exhaust ports are CNC-profiled to
match Edelbrock #7236, or Fel-Pro #1413 exhaust gaskets
SPARK PLUGS: Use 14mm x 3/4" reach gasketed spark
plugs.
Heat range may vary by application, but we
recommend Champion RC-12YC (or equivalent) for most
applications. Use anti-seize on the plug threads to
prevent galling in the cylinder head, and torque to 10
ft./lbs. DO NOT OVERTIGHTEN SPARKPLUGS!
Lubricants: For added performance and protection, we
recommend using Edelbrock performance lubricants.
