Edelbrock Aluminum Heads for Pontiac D-Port V-8 Engines

Edelbrock Aluminum Heads for Pontiac D-Port V-8 Engines

$1,007.93

After 40-50 years, don't you think its time you treat your Pontiac to a great set of aluminum heads? Let your engine breathe with a modern design and shed a bunch of weight in the process!

Those tired old iron heads were not designed for today's low-octane, unleaded gasoline. All else being equal, we find these aluminum heads allow us to add a full point of compression on an engine build. That translates to a big jump in power. Why? Because aluminum is a much better conductor of heat than iron and that keeps detonation in check.

Just bolting them on? You'll still get the better air flow, lower weight and finally get to do something about that knocking.

Want even more than you'll get straight out of the box? Call us to tune these heads up any way you want them. We can also help you with any other parts you might need for your build.

The engine in the photo came into our shop old and tired. With a set of Edelbrock Performer RPM heads and a new hydraulic roller cam, this bad boy left with 525 hp.

PERFORMER® D-PORT HEADS (389-455 cid)

Performer Pontiac Cylinder Heads utilize a D-Port exhaust port configuration for use with standard D-port exhaust systems. They are designed for 1962-79 389, 400, 421, 428 and 455 c.i.d. V8 Pontiac engines with a 4.060" or larger bore.

They feature optimized oil return passages for increased oil flow. These heads are available in three heart shaped combustion chamber sizes, including 65cc, 72cc and 87cc. The combustion chambers are fully CNC’d to provide a 9.5:1 compression ratio when used with flat-top pistons. The spark plug has been relocated closer to the exhaust valve for improved performance. These heads are cast with extra thick port walls and a compact port size, making them ideal for CNC and hand porting. Complete cylinder head includes guide plates, rocker studs and high-quality valvetrain for direct bolt-on application. Heat crossover is machined for 50-state emissions legal performance.

IMPORTANT

THESE HEADS HAVE D-PORT TYPE EXHAUST PORTS. PLEASE CHECK OUR OTHER ADS FOR RAM AIR IV TYPES.
