After 40-50 years, don't you think its time you treat your Olds to a new set of great 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 will 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.

By the way, the picture above is posted on our Facebook page. With a set of these heads and a hydraulic roller cam, this bad boy pushed out an amazing 548 lb-ft of torque and 502 hp.
