PLEASE study these instructions carefully before beginning this installation. Most installations can be accomplished with common tools and procedures.
However, you should be familiar with and comfortable working on your vehicle. If you do not feel comfortable performing this installation, it is
recommended to have the installation completed by a qualified mechanic. If you have any questions, please call our Technical Hotline at: 1-800-416-
8628, 7:00 am - 5:00 pm, Pacific Standard Time, Monday through Friday.
IMPORTANT NOTE: Proper installation is the responsibility of the installer. Improper installation
will void your warranty and may result in poor performance and engine or vehicle damage.
DESCRIPTION: Edelbrock offers several valve covers for several engine models. See the catalog for application listing. Installation is the same as original
equipment valve covers. All covers require that baffles be installed if breathers are used. Some racing valve covers require that holes be machined for
breathers if breathers are desired. Signature Series valve covers include baffles. Check for clearance between baffles and rocker arms. Trim baffles
slightly if necessary. Edelbrock valve cover gaskets are recommended to ensure a tight seal and perfect fit. Refer to the table below for
the recommended gasket part number for your application.
INSTALLATION NOTES FOR EDELBROCK VALVE COVERS:
•
For applications using breathers/PCV, attach the breather baffles using the supplied drive pins or self-tapping
screws. If your valve covers include drive pins, use a punch and hammer to tap the pins in until fully seated
(See Fig. 1). On valve covers without breather holes, the breather holes must be drilled/machined before
attaching the baffles.
CAUTION!: WHEN DRIVING THE PINS INTO THE VALVE COVER, YOU MUST SUPPORT THE BACK SIDE OF
THE VALVE COVER WITH A BLOCK OF WOOD, OR OTHER NON-MARRING SURFACE. FAILURE TO DO SO
COULD RESULT IN DAMAGE TO THE COVER, SUCH AS CRACKS, DENTS, ETC. (See Fig. 1).
Recessed Baffles: Some valve covers include baffles with a curved recess across them. Make note of the
•
position of the baffle. The recess in the baffle plate should be positioned as shown below (See Fig. 2).
Breather Knockouts: Centerbolt covers are intended for use with OEM breather and PCV valve. If the
•
application calls for non-OEM push-in breathers, remove the "knockout ring" from the breather holes using
a hammer and a large punch. Be sure to support the perimeter of the breather hole with a large socket, or
block of wood. Perform this procedure BEFORE installing the breather baffles.
•
Pontiac: Elite Valve Covers #4256 for Pontiac V8s will require that spacers be used to provide clearance for
the A/C compressor bracket. Install the spacers under the bracket at the intake manifold. Signature Valve
Covers #4457 will not allow for factory A/C bracket that extends over the valve cover.
Small Block Chevrolet: 1986 and earlier Small block Chevrolet engines with EGR may require #1476 and/
•
or GM #14031368 spacers to provide clearance for the EGR valve, especially with "tall profile" valve covers.
Big Block Chevrolet: Rocker arm to valve cover clearance must be checked before installing the valve covers. Some roller rockers may contact
•
the inside corner of the valve cover. If evidence of this contact is seen, it is recommended to have the corner of the rocker arm radiused slightly to
allow sufficient clearance throughout its full travel.
NOTE: Remember to always check Rocker Arm clearance before fully installing the Valve Covers. A good way to verify clearance is to install the
covers without bolts, then slide them until they make contact. Verify the clearance by checking the offset of valve cover bolt holes with the head
holes. A minimum of 0.060" of clearance is sufficient.
