Eliminate Blown Head Gaskets on Your 6.0L Powerstroke – The Ultimate ARP Upgrade
The Ford 6.0L Powerstroke is legendary for power — and infamous for head gasket failures. Factory torque-to-yield head bolts stretch and lose clamping force under even moderate boost or tuning. The ARP 250-4205 Custom Age 625+ Head Stud Kit solves this problem permanently with the strongest material ARP offers for this engine.
Built from ARP’s exclusive Custom Age 625+ superalloy (a chromium-cobalt-nickel formulation), these studs provide a minimum 260,000 psi tensile strength (typically rated near 270,000 psi) — roughly 40% stronger than OEM bolts and significantly tougher than standard ARP 2000 studs. This extra strength delivers the clamping force needed to keep cylinder heads locked down under extreme combustion pressures.
Whether you’re fixing a blown head gasket, building a high-horsepower daily driver, or chasing big boost for sled pulling or competition, these are the head studs serious 6.0L owners choose.
Key Benefits
- Prevents cylinder head lift and blown head gaskets — even at high boost levels
- Superior fatigue strength, toughness, and corrosion resistance
- Heat-treated before thread rolling for maximum strength
- Centerless ground for perfect concentricity
- Shot-peened and black oxide coated for durability
- Reusable studs (unlike single-use factory TTY bolts)
- Includes everything needed for a complete, professional install
What’s Included
- 20 × Custom Age 625+ Head Studs
- 20 × Hardened Parallel-Ground Washers
- 20 × 8740 Chrome Moly 12-Point Nuts
- 10 × 8740 Bolts & Washers (intake-side / inner row)
- ARP Ultra-Torque Fastener Assembly Lubricant
- Installation Instructions

- 2003–2010 Ford E-250 / E-350 Econoline Vans (6.0L)

Note: Professional installation is strongly recommended. Always use the included ARP Ultra-Torque lubricant and follow ARP’s specified torque procedures. This kit includes the inner-row M8 head bolts (ARP 250-4206 equivalent).
