High-strength, high-performance heads.
Designed and developed by Mopar Performance Parts, these Stage VI heads are made from high-strength aluminum and are designed to be completely interchangeable with the stock B/RB cylinder heads. These heads feature high-strength lightweight aluminum construction, larger intake ports that are rectangular and raised for increased output, and raised exhaust ports, while maintaining the stock header pattern. Their closed combustion chamber with a thick .450 in. deck permits milling, and they use the stock valve gear. These heads are quality checked for pressure and hardness, and include seats and bronze 3/8 in. valve guides.
