The ARP Header Bolt Kit – 6pt. 5/16 x .750 UHL (14) is a premium fastening solution engineered for high-performance Mopar V8 engine builds. This set of 14 chromoly header bolts delivers the strength and reliability required for serious engine assembly work, whether you're building a race engine, restoring a classic muscle car, or upgrading an existing powerplant. The black oxide finish provides corrosion resistance and professional appearance, while the chromoly construction ensures superior tensile strength compared to standard fasteners.
Each bolt in this kit features a 5/16-18 thread specification with a 0.75-inch length and hex head design, engineered to OEM and performance standards for Mopar V8 applications. The 6-point head design provides superior grip and reduced fastener wear compared to 12-point alternatives, critical when working with precision engine assembly where bolt torque specifications must be held consistently. Chromoly material offers higher strength-to-weight ratio than standard steel, enabling tighter torque values and more reliable clamp load under extreme combustion pressures and thermal cycling.
This kit is purpose-built for intake manifold and header mounting on Mopar V8 engines where fastener integrity directly impacts engine sealing and performance. The 14-bolt configuration covers typical header and intake manifold bolt requirements on most Mopar big-block and small-block V8 platforms. Builders who prioritize durability, proper clamping force, and long-term reliability specify chromoly fasteners over standard hardware for engine work where repeated thermal stress and vibration are factors.
ARP is recognized in the automotive performance industry for manufacturing fasteners to exacting standards, with quality control and material verification built into every product. For engine builders and restorers serious about assembly integrity, this header bolt kit provides the confidence that fastening won't be a failure point during high-stress engine operation.
