Ford Head Stud Kit 6pt.

The ARP Ford Head Stud Kit 6pt. (part number 156-4101) is a high-performance fastening solution designed specifically for Ford modular engine platforms. This kit is ideal for engine builders and performance enthusiasts looking to enhance the integrity of their cylinder heads, especially in high-stress applications such as boosted or heavily modified engines.

Constructed from durable chromoly steel and finished with a black oxide coating for corrosion resistance, this head stud kit ensures consistent preload across all fastening points. The hex nut design allows for precise torque application during installation, which is crucial for maintaining proper gasket sealing and preventing head lift under peak combustion pressures.

Engine builders and performance shops working on naturally aspirated and forced-induction Ford modular motors—including 4.6L, 5.0L, and their derivatives—will find this kit invaluable. By redistributing clamp load more evenly than traditional bolts, it reduces the risk of gasket failure and catastrophic head separation, making it suitable for both mild stroker builds and extreme competition engines.
