Key Features

ARP High Performance Series head bolt kits incorporate several advanced features to ensure superior performance and durability. These features include:

• Material and Construction: Made from chromoly steel, these bolts offer exceptional strength and resistance to stretching under high cylinder pressures. The chromoly composition provides a 15 percent increase in strength over traditional Grade 8 fasteners, rated at 180,000 psi.
• Finish and Corrosion Resistance: The black oxide finish not only enhances the appearance but also provides excellent corrosion resistance, ensuring long-lasting performance in various environmental conditions.
• Design and Compatibility: The kit features a hex head design for reduced wrenching effort and ease of installation. The undercut stud design eliminates the need for valvetrain removal during re-torque procedures, saving time and effort during maintenance or assembly.
• Washers Included: The kit comes complete with high-quality washers, ensuring proper load distribution and sealing integrity for reliable operation.
• Versatility: Designed to fit multiple Buick models, these head bolts are suitable for a range of engine configurations, making them a versatile choice for various rebuild projects.

Construction & Design

These ARP head bolts are meticulously engineered with a focus on strength, durability, and ease of use. The chromoly steel construction provides a significant strength advantage over standard fasteners, helping to maintain proper head gasket sealing under high combustion pressures. The black oxide finish not only offers corrosion resistance but also reduces glare in the engine bay, contributing to a cleaner appearance.

The hex head design allows for straightforward installation and removal, even in tight engine compartments. The undercut stud design minimizes the need for valvetrain disassembly during re-torque procedures, simplifying maintenance and reducing downtime. Each bolt is manufactured with precision threads and a controlled stretch to ensure consistent clamping force across all fasteners, promoting reliable engine operation.

Performance & Reliability

Rated at 180,000 psi, these ARP head bolts are 15 percent stronger than traditional Grade 8 fasteners, providing enhanced resistance to stretching and failure under high-stress conditions. This increased strength helps support higher compression ratios, boost levels, and aggressive driving styles, making them suitable for both street and race applications. Their robust design ensures that your cylinder heads remain securely fastened, preventing leaks and maintaining optimal engine performance.

Installation & Fitment

Designed as a direct bolt-on replacement, these head bolts require no modifications or special tools for installation. Proper torque specifications should be followed as per ARP's instructions to ensure optimal clamping force and sealing. The kit is suitable for a range of Buick engines, and the included washers help achieve a proper seal and load distribution. No valvetrain removal is necessary during re-torque, thanks to the undercut stud design, making maintenance straightforward and efficient.
