Ford Racing Super Cobra Jet Cylinder Head - Assembled with Dual Springs

If you're looking to get the most out of your 429 big block Ford, these Ford Racing Super Cobra Jet cylinder heads are a serious upgrade. Developed in partnership with Jon Kaase, these heads are designed to significantly improve airflow and combustion efficiency, translating to more power for your performance build. They represent a substantial step up from the already potent standard Cobra Jet heads.

The key to the Super Cobra Jet's improved performance lies in its revised valve angles and locations. This redesign helps reduce shrouding around the cylinder walls, allowing for better air and fuel mixture entry and exit. The combustion chambers have also been reconfigured to work with these new valve placements, ensuring a more efficient burn. These heads come fully assembled, utilizing the same robust valves, dual valve springs, retainers, and 7/16 inch stud-mounted roller rockers found in current Ford Racing 429 Cobra Jet heads, making installation straightforward. Standard Cobra Jet intake and exhaust manifolds will bolt right up, simplifying the integration into your existing setup.

Depending on your engine's displacement and camshaft choice, you can expect a 25-50 horsepower increase over the standard Cobra Jet heads. This makes them an excellent choice for drag racing or any application where maximum power output from a 429 is the goal. Please note that these heads are not CARB approved and cannot be shipped to California.
