INSTALLATION INSTRUCTIONS

®

PLEASE

study these instructions carefully before beginning this installation. Most installations can be accomplished with common tools and

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 aluminum 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 ALUMINUM VALVE COVERS (4100 & 4200 SERIES PART NUMBERS):

•

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.

•

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:

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.
