Edelbrock Big-Block Chrysler E-Street Cylinder Heads 84cc Installation Instructions
for B / RB Big Block Chrysler V8s
Part #5090, 5093
Please study these instructions carefully before installing your new cylinder heads. If you have any questions, do not hesitate to contact our Technical
Hotline at: 1-800-416-8628, 7:00 am - 5:00 pm, Monday through Friday, Pacific Standard Time.
DESCRIPTION: Designed for non-emissions 1961-1978 Chrysler B
361, 383 and 400 c.i.d. engines and RB 413, 426 wedge and 440 c.i.d.
engines. #5090 features a 75cc combustion camber which can be used
with stock pistons to retain the 9.5:1 compression ratio. #5093 feature
an 84cc combustion chamber which allows for near stock compression
when using the correct head gaskets. These cylinder heads also
feature 210cc intake ports and 70cc exhaust ports. Other outstanding
features include phosphor-bronze valve guides, interlocking, ductile iron
valve seats and premium one-piece, stainless steel, high-flow 2.140”
and 1.810” intake and exhaust valves. Heat-treated, machined steel
retainers and valve locks long with heavy duty valve springs work with
cams having valve lifts up to .600”. These powerful heads use the stock
location for intake flange and bolt holes, rocker shafts, and valve cover
rails, for compatibility with original equipment and aftermarket parts.
Exhaust flange has been extended out .125” in order to provide dry
exhaust bolt/stud holes. Exhaust bolt holes feature helicoil thread inserts
for added strength and durability.
The complete cylinder heads are assembled with the following
q Stainless steel, one-piece, swirl-polished intake and exhaust
valves with under-cut stems for increased flow
q 2-ring positive oil control seals
q Edelbrock Sure-Seat valve springs #5792
q Retainers #9644
q Valve keepers #9616
q Valve spring seats #5771
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.
For a successful installation, the Edelbrock E-Street Cylinder Heads
require some components other than original equipment parts. To
complete your installation, you will need the following items:
Head gaskets; Edelbrock #7325, Fel-Pro #1009, or equivalent
(see installation instructions).
Intake manifold gaskets; Fel-Pro #1214 for B 361-400 c.i.d.
and #1215 for RB 413-440 c.i.d. or equivalent. Edelbrock
#7225 may be used in either application, when a stock style
valley pan is used.
Exhaust gaskets; Fel-Pro #1414 or equivalent
NOTE: Edelbrock Cylinder Head Gasket Set #7366 may also
be used in place of individual gaskets. This set contains all
gaskets necessary for cylinder head installation, including
cylinder head, intake (requires stock type valley pan), exhaust,
and valve cover gaskets.

CHECKING PISTON-TO-VALVE, PISTON-TO-BORE AND PISTON-TOHEAD 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 to your pistons may be required. Actual valve-topiston clearance should be specified by your camshaft manufacturer.
Valve-to-bore clearance should also be checked, and the top of the bore
notched for clearance, if necessary.
SPECIAL NOTE: Use P/N 60149/60919 (Bare), P/N 60189/60929 (Flat
Tappet), or P/N 60185/60925 (Hydraulic Roller) for high compression 440
engines with above deck piston height. (Pistons protrude above the deck
on the block). In all cases, you must make sure that there is at least
.035” clearance between the piston and any part of the cylinder heads.
ACCESSORIES: Although Edelbrock E-Street Cylinder Heads will
accept OEM components (valve covers, intake manifold, etc.), we highly
recommend that premium quality hardware be used with your new
Head Bolts or Studs: High quality head studs or head bolts with
hardened washers must be used to prevent galling of the aluminum bolt
bosses. Edelbrock head bolt kit #8591 includes all bolts which must be
used with these cylinder heads.
Rocker Arms and Valve Train: Adjustable rocker arms must be used
with cams having greater than stock valve lift. We recommend original
equipment or aftermarket adjustable rocker arm assemblies, along with
matching pushrods. Use supplied spacer shims as needed to ensure
adequate clearance between pushrods and intake port walls. CAUTION:
Before installing rocker shafts, check for burrs or other obstructions on
the machined saddles where the shaft sits. Remove any burrs and clean
saddles thoroughly, if necessary.
Valve Covers: Edelbrock E-Street cylinder heads accept 1963 and later
stock valve covers. They also will accept Edelbrock valve covers #4491.
Intake Manifold: Although stock intake manifolds will fit, Edelbrock

E-Street Chrysler Cylinder Heads are matched in size and operating
range with Edelbrock Performer Intake Manifolds #2186 for B engines
and #2191 for RB engines. Edelbrock #7225 intake gaskets (if used
with stock style valley pan - “B” or “RB” engines), Fel-Pro intake
manifold gaskets #1214 for “B” and #1215 for “RB” engines, and Mopar
performance #P4286825 for “B” and #P4286826 for “RB” engines
are recommended. Follow the manifold or gasket manufacturer’s
recommendations for installation.
Exhaust Headers: Some headers or exhaust manifolds designed for
original equipment heads will have reduced spark plug boot clearance.
Check and make sure there is enough header/manifold-to-spark plug
ports are CNC-profiled to match Fel-Pro #1414 exhaust gaskets which
are recommended for this application.
continuous 1/8” bead of automotive RTV silicone sealer to end sealing
surfaces on block and along bottom of intake ports on cylinder head.
Also, apply a thin bead of sealer around intake ports on cylinder head
and gasket. Position intake gasket thin valley cover in place and tighten
bolts down. Then, place intake manifold in position and torque manifold
bolts to 25 ft. lbs.
Notes: 1) Rocker shaft hold-down studs, nuts and washers for 2 places
marked (S) in each head are supplied in this kit. 2) Double nut both
studs and screw them in until they reach the bottom. Install rocker shaft,
factory concave washer and hard washer supplied with this kit. Apply
30W oil to fine threads and under nuts and washers and torque nuts to
25 ft./lbs. A head bolt re-torque is recommended after initial start-up
and cool-down (allow 2-3 hours for adequate cooling).

Spark Plugs: Use 14mm x 3/4” reach gasketed spark plugs. Heat
range may vary by application, but we recommend Champion RC-12YC
(or equivalent) for most applications. Use anti-seize on the plug
threads to prevent galling in the cylinder head, and torque to
10 ft./lbs. Do not overtighten sparkplugs! If short reach plug is
used, poor performance and possible engine damage may occur.
INSTALLATION: Installation is the same as for original equipment
cylinder heads. Consult service manual for specific procedures, if
necessary. Be sure that the surface of the block and the surface of the
head are thoroughly cleaned to remove any oily film before installation.
Use alcohol or lacquer thinner on a lint-free rag to clean. Apply oil or
suitable thread lubricant to head bolt threads and the underside of bolt
heads and washers. Torque to 70 ft./lbs. in three steps (40, 55, 70)
following the factory tightening sequence (see Figure 1). Apply a
