Ford Racing teamed up with Jon Kaase to redesign their 429 Cobra Jet cylinder heads, and the results are these Super Cobra Jet heads. They feature revised valve angles and locations to reduce cylinder wall shrouding and improve flow, along with redesigned combustion chambers to accommodate the more centrally located valves. These heads use the same valves, valve springs, retainers, and 7/16 in. stud-mounted roller rockers as the current Ford Racing 429 Cobra Jet heads, and the standard Cobra Jet intake and exhaust manifolds bolt right on. This new design offers a 25-50 HP increase over current Cobra Jet heads, depending upon displacement and camshaft.
- Revised Valve Angles And Locations
- Redesigned Combustion Chambers

Super Cobra Jet Heads
Ford Racing brings to you the Super Cobra Jet Aluminum Cylinder Heads. Thess big block cylinder heads are the perfect combination to your fit your 429 or 460 Big Block Ford. Ford Racing Designed this latest generation on an old classic name to deliver high output performance in a lightweight, cast-aluminum package.

This gives you all that big block low end torque without any loss in midrange or high end horsepower.
