Overview

The ARP Head Bolt Kits are high-performance fasteners designed to provide a reliable and durable connection between your engine's cylinder heads and the engine block. Built with strength and precision in mind, these head bolt kits are ideal for enthusiasts and professionals seeking to ensure the integrity of their engine during rebuilds, upgrades, or high-performance applications. Whether you're restoring a classic muscle car or building a high-horsepower street machine, ARP's head bolts deliver peace of mind and consistent performance.

Constructed from top-grade materials and engineered for maximum strength, these head bolts help support increased horsepower and torque, while maintaining proper clamping force under demanding conditions. Their robust design minimizes the risk of head gasket failure and ensures proper cylinder head sealing, which is critical for optimal engine performance and longevity.

Key Features

ARP High Performance Series head bolt kits are engineered to meet or exceed OEM specifications, offering a significant upgrade in strength and reliability. Crafted from high-strength alloy steel rated at 180,000 psi, these bolts are approximately 15 percent stronger than standard Grade 8 fasteners, providing enhanced durability for high-stress engine environments.

• Rated at 180,000 psi for superior strength and durability
• Available with a reduced wrenching hex head or 12-point head for easier installation and re-torqueing
• Designed to eliminate the need for valvetrain removal when re-torqueing cylinder heads, saving time and effort
• Precision-machined threads and under-head fillets for optimal fit and clamping force
• Made from high-quality alloy steel for maximum strength and corrosion resistance
• Engineered for use in high-performance and stock rebuild applications
• Suitable for a range of GM small-block V8 applications from 1997 to 2004

Construction & Design

These ARP head bolts feature a high-strength alloy steel construction, meticulously machined to exact specifications to ensure perfect fitment and consistent clamping force. The bolts are heat-treated to achieve optimal hardness and strength, providing long-lasting performance even under extreme conditions. The design includes a reduced wrenching hex head or a 12-point head option, allowing for easier access in tight engine bays and simplifying the re-torque process during maintenance or upgrades.

The threads are rolled for increased fatigue strength and smooth engagement, while the under-head fillets are radiused to reduce stress concentrations. This attention to detail in manufacturing ensures that each bolt maintains its integrity over countless thermal cycles and engine rebuilds, making it a reliable choice for performance and restoration projects.

Installation & Fitment

The ARP Head Bolt Kits are designed for straightforward, bolt-on installation. They are compatible with 1997–2004 Chevrolet Corvette and 1998–2002 Pontiac Firebird models equipped with 5.7L V8 engines. No special tools beyond standard socket sets are required. It is recommended to follow ARP's specified torque sequence and settings to ensure proper clamping force and sealing. No valvetrain removal is necessary for re-torqueing, simplifying routine maintenance and head gasket checks.

• Easy to install with standard hand tools
• Designed for use in stock rebuilds and high-performance applications
• Ensure proper torque sequence for optimal results
