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.

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 Fel-Pro #1413 exhaust gaskets which are

recommended for this application.

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!

INSTALLATION
Installation is the same as for original equipment cylinder

heads. Consult service manual for specific procedures, if

necessary. 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 oil or suitable thread lubricant to

head bolt threads and under side of bolt heads and washers.

Torque to 95 ft./lbs. in three steps (45-65-95) 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).

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.

VALVE COVERS: Edelbrock Performer RPM heads accept

stock valve covers for the year and model for which they are

listed. Part #60779 & #60179 will accept Edelbrock valve

covers #4495 or #4295.

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. 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
