Fleece Performance 5.9L Freedom Series Cummins Cylinder Head Street - FPE-61-10005

Freedom Series cylinder heads - Give new life to your engine with our fully remanufactured Cummins cylinder head. Each head is manufactured in our state-of-the-art cylinder head machine shop and guaranteed to meet or exceed factory specifications.

All heads are inspected, pressure checked, decked, painted, and ready for installation. Plus, the 11 screw in freeze plugs ensure you'll never worry about a coolant leak under the valve cover again.

Perfect for a daily driver or heavy duty towing, our Street heads are rated for use up to 700hp. If your engine configuration is exceeding factory RPM limits a Performance Series head with higher valve spring rates is required.

Freedom Series Street heads Include:

• 11 Screw in Freeze Plugs (eliminates coolant leaks)
• Hardened, oversized press-in valve seats
• New Cummins valve springs
• New valve guide liners

Notes:

• Head gasket not included. We recommend the use of Cummins 3958645.
• Core and crate return required - all paperwork and instructions for return included with the new cylinder head. You are responsible for all return shipping costs of the core.
• Follow all installation instructions; Valve lash required. Back off adjusters on rocker arms or damage will occur to the cylinder head. For all applications over stock horsepower we recommend the use of ARP625 or ARP L19 12mm head studs.
