If you're looking to give your Ford 429 a serious boost, you might want to check out the Super Cobra Jet cylinder heads that Ford Racing developed with Jon Kaase. These aren’t just any heads; they’ve been thoughtfully redesigned to really maximize performance. The valve angles and locations have been adjusted to minimize cylinder wall shrouding, which is a fancy way of saying they help improve airflow. And the combustion chambers? They’ve got a new layout that centers the valves better, leading to even more efficiency.

What’s cool is that these heads still use the same valves, valve springs, retainers, and 7/16 in. stud-mounted roller rockers as the existing Cobra Jet heads. So, if you’ve already got some parts on hand, you won’t have to worry about a complete overhaul. Plus, the standard Cobra Jet intake and exhaust manifolds bolt right on without any fuss. With this setup, you can expect a solid 25-50 horsepower increase, depending on your engine's displacement and camshaft choice. That’s a noticeable difference on the street or at the strip!

These heads come as bare units, so you’ll need to have a pro prep them before installation. But trust me, the performance gains are worth it. Whether you're hitting the drag strip or just cruising around town, these Super Cobra Jet heads are a fantastic upgrade for any Ford 429-460 engine.
