DESCRIPTION: The Edelbrock E-Street Cylinder Heads are designed for street use on small block Ford 289, 302 and 351W engines. They are sold in pairs, both bare and assembled, with either 1.90" or 2.02" intake valves. E-Street heads do not include exhaust crossovers or air injection passages and may not be street legal in emission controlled applications. Edelbrock cylinder heads offer "out-of-the-box" bolt-on performance with no additional porting required. The performance range is from idle to 5500 rpm for great throttle response as well as top-end horsepower. These cylinder heads are assembled with the following components: Stainless steel one-piece intake and exhaust valves; 2-ring positive oil controls seals; 3/8" rocker studs and 5/16" guideplates. Complete cylinder heads are assembled with hardened valve spring seats and prepared for installation right out of the box. 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 cam kit and Performer or Thunder AVS Series Carburetors.
IMPORTANT NOTE: E-Street Cylinder Heads are equipped with 1.25” diameter valve springs that have been tested to 5,500 rpm. DO NOT EXCEED 5,500 RPM WITH THESE SPRINGS. Higher operating speeds may induce valve float which can cause severe engine damage. Performer RPM heads are recommended for higher engine speeds.
ACCESSORIES: Although Edelbrock E-Street Cylinder Heads will accept most OEM components (stud-mounted 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.

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). 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. 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: Edelbrock E-Street Cylinder Heads are designed to work with stud-mounted rocker arms only. If your engine is equipped with late model pedestal mount rocker arms you will need to purchase and install stud mounted rocker arms, such as Edelbrock Rocker Set #77780. The valve springs supplied will accommodate valve lifts up to .550", 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. Use Edelbrock Signature Series chrome valve covers #4260, or cast aluminum Classic valve covers #4160 for a matching fit and finish. Intake Manifold: Although stock intake manifolds will fit, the Edelbrock E-Street Cylinder Heads are matched in size and operating range with Edelbrock Performer and Performer RPM intake manifolds. Please note that E-Street cylinder heads are not compatible with Performer RPM camshafts. If these manifolds are too tall to fit under your hood, you may use the Edelbrock Torker II manifold (#5021 or #5081).
Exhaust Headers: Any header or manifold designed for original equipment heads will fit the Edelbrock E-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. Champion RC12YC is the recommended plug to start with for most applications, modifying the heat range from there as needed. 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: Edelbrock head gaskets #7313 are recommended for use with E-Street heads. Edelbrock Cylinder Head Gasket Set #7364 may also be used. This gasket set includes all gaskets necessary for installation of Edelbrock cylinder heads, including cylinder head, intake manifold, exhaust and valve cover gaskets.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: If 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 in Figure 1 on the next page, and the at same location on the surface of the block to prevent coolant from contaminating the oil.
a) Late model 289-302 blocks have the water passages located next to the head bolt location on the deck of the block (This block will not require drilling). b) Early 289-302 blocks will have the water passages located directly over the cylinder upper deck area and will require drilling 1/8" steam holes as seen in Figure 2.
