What is the difference between head studs and head bolts?

Confirm fitment using our detailed application guide to ensure compatibility for your specific vehicle before installation.
ARP Head Stud Kits deliver superior clamping force, achieving an 8 out of 10 score for Track/Autocross performance by enhancing seal consistency. Featuring Ford Modular 4.6L 2&4 Valve 12 pt design, these kits guarantee extreme engine reliability and prevent costly leaks. Trust ARP for unparalleled performance and unwavering confidence in your engine's integrity.
What Owners Say
Owners and enthusiasts consistently point to ARP's manufacturing quality as the standout feature, noting they almost never have defects and deliver reliable performance under demanding conditions like boost applications. Users report successful installations using ARP torque specs, with head studs providing superior clamping force and even pull on heads compared to factory bolts, which is especially critical for large-bore engines. The design stretches to approximately 75% of yield point rather than to yield like GM bolts, making them reusable. While some builders debate whether budget alternatives like Exotic offer comparable performance at lower cost, ARP remains the benchmark that other manufacturers are measured against in the performance engine community.
