SBC Head Stud Kit

The ARP Small Block Chevy Head Stud Kit (Part Number 134-4310) is a chromoly fastening system designed for small block Chevy engines equipped with aftermarket cylinder heads. Head studs replace factory bolts with a superior fastening method that maintains consistent clamping load under extreme heat and cylinder pressure cycling, critical for engines experiencing sustained high-RPM operation or forced induction applications.

This kit features chromoly construction with a black oxide finish, providing both strength and corrosion resistance. The 12-point nuts deliver improved grip geometry compared to traditional 6-point designs, reducing fastener slippage during installation and removal cycles. ARP studs are manufactured to tight tolerances and specify proper torque sequences to ensure even load distribution across all head bolt locations—a critical factor in maintaining head gasket integrity and preventing blow-out in high-performance or turbocharged small block applications.

Engine builders and serious enthusiasts rely on ARP stud kits as standard practice when assembling small block Chevy platforms for racing, street performance, or reliability upgrades. The studs accommodate most aftermarket cylinder head configurations and are compatible with standard small block Chevy engine blocks, making this kit a foundational upgrade for any power-increase project. Proper installation with supplied hardware and recommended torque specifications is essential for optimal performance and longevity.

ARP is recognized as the industry standard for engine fastening systems, with decades of application in professional racing and street performance builds across all major motorsport disciplines.
