ARP Small Block Chevy Cylinder Head Hex Bolt Kit 134-3601 — High-Strength Vehicle-Specific Fasteners

ARP 134-3601 is a precision-engineered cylinder head hex bolt kit designed specifically for Small Block Chevrolet engines, delivering consistent clamping force for high-performance applications.

This ARP High Performance Series cylinder head bolt set (P/N 134-3601) supplies reliable, vehicle-specific fasteners for Small Block Chevy installations. Manufactured by ARP, a leader in aftermarket fasteners, this kit replaces OE head bolts with hardened hex head bolts intended to maintain correct torque and clamp load under repeated thermal and mechanical stress. The package weighs approximately 5.0 pounds and is tailored for mechanics, engine builders, and enthusiasts seeking durable head fastening hardware.

Why choose ARP 134-3601 over factory bolts?

ARP bolts are made from high-strength materials and produced to tighter tolerances than many stock fasteners, improving longevity and reducing the chance of head gasket failures due to bolt stretch. These hex head bolts are engineered to deliver predictable torque-to-yield behavior and more repeatable clamp loads during assembly and maintenance.

• High-strength material specification for improved fatigue resistance
• Consistent clamp load for reliable head sealing
• Precision manufacturing reduces dimensional variation
• Designed for repeated removal and installation

How does this kit fit Small Block Chevy engines?

The ARP 134-3601 kit is vehicle-specific for Small Block Chevrolet applications and matches the common bolt pattern and lengths required for SBC cylinder heads. Using a kit designed for the engine ensures proper engagement with the block and correct compression of head gaskets.

• Part number 134-3601 corresponds to SB Chevy configurations
• Bolt lengths and hex head form match OEM requirements
• Fit type labeled as vehicle specific for accurate compatibility

What benefits do hex head bolts offer during assembly and maintenance?

Hex head fasteners provide a familiar, accessible head style for torqueing with standard tools and simplify installation in tight engine bays. They are easier to handle during workshop procedures and require common sockets or wrenches for correct torque application.

• Uses standard hex sockets/wrenches available in most toolkits
• Straightforward torque and re-torque procedures
• Good clearance for ratchets in confined engine spaces

What should you consider when replacing head bolts?

When installing new cylinder head bolts, follow the engine manufacturer's recommended torque sequence and values, or ARP's published installation instructions if provided. New high-strength bolts may require specific torque and stretch procedures, and using a calibrated torque wrench or angle gauge ensures correct clamp load.

• Always replace bolts in complete sets for balanced clamping
• Use proper torque sequence and specified torque/angle values
• Inspect threads and clean bolt holes before installation
• Consult ARP or engine builder guidance for lubrication and torque specs

Who is this for: The ARP 134-3601 cylinder head bolt kit is intended for automotive technicians, engine builders, and performance-minded owners working on Small Block Chevy engines who want a durable, vehicle-specific replacement for factory head bolts. It suits rebuilds, performance upgrades, and restorations where reliable head clamping and repeatable torque behavior are priorities.
