DESCRIPTION
Designed for 1965-1979 389-455 c.i.d. Pontiac engines, these heads are patterned after the 1969-1970 Ram Air IV Pontiac cylinder head. Two styles
are available: 87cc combustion chamber version for applications requiring an 87cc combustion chamber and a 72cc chamber version for applications
requiring a 72cc combustion chamber. Both heads have Ram Air IV port flanges. Performer RPM Pontiac heads produce outstanding horsepower with
excellent low speed torque and throttle response. High flow exhaust ports require Ram Air IV headers or exhaust manifolds. On both versions, the deck
surface is 5/8" thick for superior durability and head gasket retention. All factory accessory bosses are included for bolt-on convenience. Performer
heads #60569 and #60579 have the exhaust heat cross-over machined and are street legal on 1965-1979 vehicles with 389-455 c.i.d. V8s without
secondary air injection. Note: In 1967-1968 Pontiac, change valve angle from 17° to 14°. Edelbrock Pontiac cylinder heads use the later 14° valve
angle. When installing Edelbrock Pontiac cylinder heads on 1965-1966 and some 1967 engines that came stock with the early 17° valve angle,
compatibility of valves with pistons will need to be checked.
* Not legal for sale or use on pollution-controlled motor vehicles.

#60509 is a semi-machined version of the 72cc chamber head. Designed to be finished by professional cylinder head porters, this version comes with
valve guides and seats installed, but with no port machine work or intake pushrod holes. Complete heads are assembled with stainless steel, one-piece
swirl-polished 2.11" intake and 1.66" exhaust valves with under-cut stems to promote excellent flow for more power. They also include 2-ring positive
oil control seals, 7/16" rocker studs and 5/16" guideplates, Edelbrock Sure-Seat Valve springs #5767, retainers #9736, valve spring seats #5769, valve
stem seals #9725 and valve keepers #9611. Complete cylinder heads are assembled and prepared for installation right out of the box.

HEAD BOLTS or STUDS: Edelbrock Head Bolt Kit #8549 must be used
with these cylinder heads. These cylinder heads will not accept stock
length head bolts. To prevent stripping of head bolts or improper torque,
you must use the correct length bolt in each location. See Figure 1 for
head bolt location.
ROCKER ARMS: The valve springs supplied will accommodate valve
lifts up to .575", which is much higher than stock rocker arms will allow.
Roller rocker arms will be required if your camshaft has more than .500"
lift. Stock rockers may require longer-than-stock pushrods to clear the
valve springs.

EXHAUST HEADERS: Any header or manifold designed for Ram Air IV
heads will fit the Edelbrock Pontiac Cylinder Heads. Exhaust ports are
CNC-profiled to a high-flow “D” shape. However, Edelbrock #7281 or
Fel-Pro #1436 round exhaust gaskets are recommended for this
application. Do not change size or shape of exhaust ports in heads!
SPARK PLUGS: Use 14mm x 3/4" reach gasketed spark plugs. Heat
range will vary by application and may range from Champion RC-9YC
to RC-14YC (or equivalent). For typical street use, Champion RC-12YC
equivalent should work well. Use anti-seize on the plug threads to
prevent galling in the cylinder head, and torque to 10 ft./lbs.
