DESCRIPTION: Designed for Ford 351-C, 351-M, and 400-M engines,
these street high-performance heads provide great "out-of-the-box",
performance for your Ford musclecar or streetrod. Performer RPM
351-C heads feature CNC profiled 190cc (intake) and 90cc (exhaust)
port exits for superior flow and efficient 60cc "Compact Charge"
combustion chambers. An optimized spark plug location provides
improved header clearance. Hardened valve seats are compatible with
any fuel. NOTE: These heads may be used in "Hybrid" applications
such as building a "Clevor" or mock Boss 302 engine. See "Hybrid
Applications" section for details.
The complete cylinder heads are assembled with the following:
Stainless steel, one-piece, swirl-polished intake (2.05") and
K
exhaust (1.60") valves with under-cut stems for increased flow
2-ring positive oil control seals
K
Edelbrock Sure-Seat valve springs #5792
K
Retainers #9734
K
Valve keepers #9612
K
Valve spring seats #5771
K
Hardened Guide Plates #9672
K
NOTE: 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.
IMPORTANT NOTES, READ BEFORE BEGINNING INSTALLATION!:
For a successful installation, the Edelbrock Performer RPM Cylinder
Heads require some components other than original equipment parts.
To complete your installation, you will need the following items:
Head gaskets; Fel-Pro #1013 (see instructions below)
K
Intake manifold gaskets; Edelbrock #7216.
K
Exhaust gaskets; Fel-Pro #1430 or equivalent
K
Cylinder head bolts or studs with hardened steel washers.
K
(If mounting on 302 block, you must also use Edelbrock head bolt
bushings with integral washers, #9680)
Heads are machined for adjustable rocker arm assembly
K
Hardened steel pushrods (For 351M/400, use Edelbrock #9633)
K
14mm x 3/4" reach gasketed spark plugs; Champion RC-12YC or
K
equivalent

IMPORTANT NOTE: Proper installation is the responsibility of the installer.

HYBRID APPLICATIONS: Cleveland heads are sometimes used in
hybrid applications such as a "Clevor" (351 Windsor block, 400-M
crankshaft, and Cleveland cylinder heads), or Boss-302 "clone" (302
Block with Cleveland cylinder heads).
cylinder heads must be drilled to provide a coolant crossover passage
for use with certain aftermarket intake manifolds designed specifically
for such hybrid engines. Guide holes are provided for this purpose
(See Figure 1) . Refer to the manufacturer of your custom intake
manifold for the appropriate location (usually the hole that will be at
the front of the block when the heads are installed) and diameter and
drill accordingly, using the guide holes to align your drill.

for Cleveland/Windsor Hybrid Applications
Additionally, the 3/4" threaded coolant holes in the deck surface of the
block must be plugged for these hybrid applications. Install the
supplied 3/4" aluminum plugs using liquid Teflon thread sealer on the
threads.
NOTE: After installing the plugs, they must be milled flush with the
deck of the cylinder head. This may require milling a small amount off
of the entire deck surface. This operation should ONLY be performed
by a professional engine machine shop.
CHECKING PISTON-TO-VALVE, PISTON-TO-BORE AND PISTON-TO-
HEAD CLEARANCES: Prior to installation, it is highly recommended
that valve-to-piston clearances are checked and corrected to
minimum specs, if necessary. These cylinder heads have larger-than-
stock valve sizes and may not work with the valve pockets in stock
pistons, especially if a high lift cam is used. The use of aftermarket
pistons and/or custom machining of your pistons may be required.
