DESCRIPTION:  The Edelbrock Performer Cylinder Head is designed for street high performance use, and is interchangeable with any early-style (1965-

75) large oval port big-block Chevrolet cylinder head.  This new cylinder head offers “out of the box” bolt-on performance with no additional porting

required.  The performance range is 1500-6500 rpm for great throttle response throughout the power band as well as top-end horsepower.  The intake

and exhaust ports are CNC machine “matched” and have been designed for maximum flow velocity when matched with Edelbrock Performer or

Performer RPM intake manifolds.  A totally unique intake port design yields flow numbers traditionally associated with high performance rectangular

port heads, but with the smaller runner size and velocity of an oval port.  The 110 cc combustion chamber is a semi-open chamber design to maximize

combustion efficiency with streetable compression ratios.  

NOTE:  This cylinder head is compatible with both early style Mark IV and late model Mark

V blocks.  

Complete cylinder heads are assembled with the following components:  Stainless steel, one-piece, swirl-polished intake and exhaust valves with

under-cut stems for increased flow; 2-ring positive oil control seals; 7/16" rocker studs and 3/8" guideplates; Edelbrock Sure-Seat Valve Springs

#5745, retainers #9715, and valve keepers #9615.  Complete cylinder heads are assembled and prepared for installation right out of the box.  

Bare

cylinder heads will have valve guides and seats installed, but will require final sizing and a valve job to match the valves you will be

using.

SPECIAL NOTICE: This Edelbrock part has received an Executive Order number (E.O.#) from the California Air Resources Board (C.A.R.B.) making it

legal for street use in all 50 states.  To assist you with emission equipment certification, we have included a silver fan shroud decal to help testing

personnel verify the this part is a legal replacement on the vehicle for which it is cataloged.  The adhesive-backed decal should be affixed next to the

existing emission and engine specifications decal.  Do not cover any part of your original emission decal.

ACCESSORIES: Although Edelbrock Street Cylinder Heads will accept

OEM components (rocker arms, valve covers, intake manifold, head bolts,

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 #8551 includes eight longer-

than-stock bolts which must be used with these cylinder heads.

If you use any other head bolts, you must use the eight head

bolts and washers supplied with these heads in positions #15,

#8, #2, and #7 in Figure 1.  THESE POSITIONS WILL NOT ACCEPT

STOCK LENGTH HEAD BOLTS.

NOTE:  BLIND BOLT HOLES

Head bolts may bottom out in blocks with blind bolt holes (Bowtie,

502 Mark V, etc.).  Check for clearance, and if necessary shorten

bolts or replace with a set specifically designed for use with blind

holes.

ROCKER ARMS:  Whether you use stock or aftermarket rocker arms, it

is recommended that geometry of the valve train be carefully checked.

The rocker arm should contact the center of the valve tip at one half of

the cam's lift and form a 90 degree angle with the stem axis at that same

half lift point.  Minor adjustments are made by moving the guide plate

and by changing pushrod length.  Chances are good that no such

adjustments will be needed if your engine is otherwise stock but you

should check to make sure.  The valve springs are designed for use with

Edelbrock hydraulic tappet camshafts.  Check that the springs are

compatible with the camshaft you have chosen.

NOTE:  ROCKER ARM TO VALVE ALIGNMENT

A visual inspection of rocker arm to valve alignment is

recommended.  In some cases, it maybe necessary to loosen the

guide plate and adjust the plate to get proper alignment.  Make

sure to re-torque the studs to recommended torque listed below.

GASKETS:

Edelbrock gasket set part #7363 includes the intake,

exhaust, head, waterneck, distributor and valve cover gaskets.

NOTE

To ensure maximum performance and a proper seal, Edelbrock

gaskets which are specifically designed and manufactured for use

with Edelbrock parts must be used.

VALVE COVERS: Because most roller rockers are physically larger than

stock rockers, taller valve covers are usually required to clear them.  Use

Edelbrock Signature Series chrome valve covers #4680 or Elite Series

polished aluminum valve covers #4280.

INTAKE MANIFOLD: Although stock intake manifolds will fit, the

Edelbrock Performer Cylinder Heads are matched in size and operating

range with Edelbrock Performer or Performer RPM intake manifolds.  For

best results, use Edelbrock intake manifolds listed as stock replacement

parts for the year and model of your vehicle.  Edelbrock part #7203 intake

manifold gaskets are recommended.  Oval port intake manifolds may be

used as-is, or port matched to the same configuration as the cylinder

heads for optimum performance.  Apply Gasgacinch Edelbrock #9300 to

intake surface of the heads.  Do not use cork or rubber end seals;

instead, use a sensor safe RTV silicone sealer.  Apply a 1/4" bead along

front and rear of block, overlapping gaskets at the four corners.  Torque

manifold bolts to 25 ft./lbs.
