Atomic SOHC INTECH H13 T/Steel 12mm Headstud Kit

Atomic Ford 6cl SOHC INTECH H-13 Tool Steel 12mm Head stud kit suit EB-AU Ford SOHC 6 cyl. Includes 12pt double hex nuts, washers and instructions.

Atomic Tool Steel Head Studs are premium fasteners designed specifically for high-performance and high-boost Ford INTECH SOHC 6cl engines. They address the limitations of conventional studs (like ARP2000 or ARP CA625+) by using a proprietary H13 ultra-high-strength tool steel—engineered to maintain clamping force under extreme cylinder pressures, RPM, and thermal cycling.

What makes them stand out:


🔧 Key Features of Atomic Tool Steel Head Studs

  • Material: Proprietary high-tensile H13 tool steel, heat-treated and tempered for superior fatigue resistance and strength retention under extreme heat and pressure.

  • Strength: Tensile strength is significantly higher than ARP2000 and ARP L19, with better performance in heat-soaked, high-horsepower applications. Ideal for 40+ psi boost levels and 1500+hp builds.

  • Thread Engagement: Precision-rolled threads for maximum surface finish and durability, reducing the risk of galling or thread pull-out in the block.

  • Stretch Properties: Exceptional elasticity range, meaning better clamping force without permanent deformation or relaxation after heat cycles.

  • Proven Performance: Used in many of Australia’s highest-horsepower Barra builds, including drag and roll-racing applications where combustion pressure and head-lift are critical concerns.

  •  Provided with: small pot of moly grease to assist assembly at correct torques
  • Torque Settings: Custom torque specifications, usually higher than typical ARP studs, to take full advantage of their superior stretch and clamping characteristics.
