Fleece Performance and Freedom Racing bring you the Street cylinder head for the 2007.5–2018 common rail 6.7L Cummins — the reliable, bolt-on foundation for daily driven, towing, and street performance builds. Every head is inspected, pressure checked, decked, painted, and ready for installation. Rated for 700 HP and ready to bolt on.

All street heads come standard with 11 screw-in freeze plugs to eliminate coolant leaks, oversized and hardened valve seats, new Cummins valve springs, and new valve guide liners. Whether you are replacing a cracked or warped head, refreshing a high-mileage engine, or building a clean platform for future modifications, the Freedom Series Street head gives you a properly built foundation with no compromises on quality.

Looking for more capability? The Heavy Duty Street head adds Fleece 105 valve springs and tool steel retainers. The Performance head steps up further with Manley stainless steel valves, fire ring cut, and a 1100 HP rating.
