DESCRIPTION: The Edelbrock Performer, Performer RPM, and Performer 5.0/5.8L Street Cylinder Heads are designed for street high performance use, and are interchangeable with original equipment small-block Ford cylinder heads. Performer Ford and Performer 5.0/5.8L heads have exhaust crossover and air injection passages and are street legal in all 50 states. Contact Edelbrock for the current E.O. number if required for emission validation. Edelbrock cylinder heads offer "out-of-the-box" bolt-on performance with no additional porting required. The performance range is 1500- 6500 rpm for great throttle response 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 either the Performer or the Performer RPM intake manifold, Performer-Plus or Performer RPM cam kit, and Performer Series Carburetors. The Performer RPM Power Package produced 400 horsepower in dyno tests on 351-W engines. These heads are designed to use 1/2" head bolts. On 289-302 engines with 7/16" head bolts, you must use Edelbrock head bolt bushings with integral washers #9680 and Edelbrock head bolt kit #8552 or stock 7/16" head bolts.
IDENTIFICATION: These heads are available individually, either bare or assembled, with either 1.90" or 2.02" (1.94 SCCA only) intake valves for the following applications:
IMPORTANT NOTE: Refer to SCCA rules specifications before performing any modifications to intake, exhaust or bowl areas.
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 controls seals; 3/8" rocker studs and 5/16" guideplates; Edelbrock Sure-Seat Valve Spring #5767, retainers #9724, valve keepers #9611. Complete cylinder heads are assembled with hardened valve spring seats 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.
ACCESSORIES: Although Edelbrock Street Cylinder Heads will accept OEM components (rocker arms, valve covers, intake manifold, head bolts [351- W only], etc., we highly recommend that premium quality hardware be used with your new heads. See our catalog for details. To order a catalog, call (800) FUN-TEAM.
Head Bolts or Studs: High quality head bolts or head studs with hardened washers must be used to prevent galling of the aluminum bolt bosses.
Recommended head bolts are ARP #254-3708 for engines with 7/16" head bolt holes (289 and 302). You may use Edelbrock Head Bolt Kit #8552 or stock 7/16" bolts on 289-302 engines only if you purchase Edelbrock head bolt bushings with integral washers #9680. Engines with ½" diameter head bolts (351-W and 302 SVO) use Edelbrock Head Bolt Kit #8553 or stock 351-W bolts with high quality head bolt washers such as ARP #200-8533. NOTE: It is recommended that 289-302 engines producing 380 or more horsepower (or with nitrous oxide) be converted to accept ½" diameter head bolts by a qualified machine shop to ensure maximum head gasket durability.
Rocker Arms: The valve springs supplied will accommodate valve lifts up to .575", which is much higher than stock rocker arms will allow. Roller rocker arms will be required if your camshaft has more than .480" lift. Stock rockers may require longer-than-stock pushrods to clear the valve springs.
Valve Covers: Because most roller rockers are physically larger than stock rockers, taller valve covers are usually required to clear them. For heads #60259, and #60359, use Edelbrock Signature Series chrome valve covers #4260, or cast aluminum Classic valve covers #4160.
Performer 5.0/5.8L heads #60379 and #60399 accept stock 5.0/5.8L valve covers, which are required for component clearance on most street applications.
Intake Manifold: Although stock intake manifolds will fit, the Edelbrock Street Cylinder Heads are matched in size and operating range with Edelbrock Performer or Performer RPM intake manifolds. If the Performer or Performer RPM is too tall to fit under your hood, you may use the EdelbrockTorker II manifold (#5021 or #5081). Additionally, any manifold that matches Edelbrock gasket #7220, or Fel-Pro gasket #1250 may be used (Edelbrock Performer, Torker II, Victor Jr., etc.)
IMPORTANT NOTE: Proper installation is the responsibility of the installer. Improper installation will void warranty and may result in poor performance and engine or vehicle damage.
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 Edelbrock #7227 or Fel-Pro #1415 exhaust gaskets, which are recommended for this application. For maximum performance, the opening of exhaust header flange should match an Edelbrock #7227 or Fel-Pro #1415 gasket.
Spark Plugs: Use 14mm x 3/4" reach gasketed spark plugs. Heat range will vary by application from Champion RC9YC to Champion RC14YC. The RC12YC is the plug used in the RPM applications (or equivalent). Use anti-seize on the plug threads to prevent galling in the cylinder head, and torque to manufacturer's specification for aluminum heads.
Head Gaskets: Head gaskets requirements change according to the application for which the cylinder heads are being used. Use the following as a guide for head gasket selection. NOTE: Certain Ford SVO Performance blocks include additional blind cooling provisions on the exhaust side of the deck surface. These holes may line up with a tooling point on the deck surface of the cylinder head (identifiable as a rough low spot), which could prevent the head gasket from sealing properly. Using the gasket as a template, verify that the head will compress the gasket above any such hole before drilling. Use a small set-screw to block this passage if necessary, on blocks in which the hole has already been drilled. NOTE: When using Fel-Pro Print-O-Seal, or any silicone beaded gasket, you must apply a small strip of silicone to both the deck flange of the cylinder head, as shown to the right, and the same location on the surface of the block to prevent coolant from contaminating the oil.
