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, 7am-5pm, Monday through Friday.
Designed for non-emissions 1967-1991 Chrysler 318-340-360 c.i.d. engines, these heads feature a 65cc combustion chamber along with
a 171cc intake port and an 77cc exhaust port volume. Other outstanding features include phosphor-bronze valve guides, interlocking,
ductile iron valve seats and premium one-piece, stainless steel, high-flow 2.02" and 1.60" intake and exhaust valves. Heat treated,
machined steel retainers and valve locks along with heavy duty valve springs work with cams having valve lifts up to .575". These
powerful heads use the stock location for intake and exhaust bolt holes and flanges, rocker shafts, spark plugs and valve cover rails, for
compatibility with original equipment and aftermarket parts. These heads are assembled with the following components: Stainless steel,
one-piece, swirl-polished intake and exhaust valves with under-cut stems for increased flow; 2-ring positive oil control seals; Edelbrock
Sure-Seat Valve Springs #5767, retainers #9736, and valve keepers #9611. 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.
You will need the following, non OEM, parts in order to successfully install the Edelbrock Performer RPM Cylinder Heads:
❑ Head gaskets; Edelbrock # 7326 or Fel-Pro #1008 (see installation instructions)
❑ Intake manifold gaskets; Edelbrock #7276, Fel-Pro #1213 or equivalent
❑ Exhaust gaskets; Edelbrock #7236, Fel-Pro #1413 or equivalent
❑ Edelbrock Head Bolt Kit #8555; (see instructions below)
❑ Adjustable rocker arm assembly
NOTE: These heads are designed to accommodate stock stamped steel rocker arm assemblies, and stock-like aftermarket
setups. Ductile iron adjustable arms may require special clearancing of the rocker arm body in order to clear valve spring
retainers. Also, non-stock spec, aftermarket rocker arms may require special modifications.
❑ Pushrods compatible with adjustable rocker arm assembly (stock length- 7.375")
❑ 14mm x 3/4" reach gasketed spark plugs; Champion RC-12YC or equivalent
Prior to installation, it is highly recommended that valve-to-piston clearances are checked and corrected to minimum specs, if necessary.
These 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-to-piston clearance should
be specified by your camshaft manufacturer.
If these heads are used on small bore engines, valve-to-bore clearance should also be checked, and the top of the bore notched for
clearance if necessary.
Special Note: Use P/N 60179 for high compression 340 engines with negative piston deck 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.
