ARP 2344314 Custom Age Head Stud Kit - 625+ 12-Point

The ARP 2344314 Custom Age 625+ Series head stud kit delivers professional-grade cylinder head clamping force for high-performance and racing engines. Featuring 12-point nuts for enhanced torque accuracy, this complete kit provides the reliability demanded by top engine builders in competition applications.

Premium Construction and Heat Treatment:

• Manufactured from premium grade 8740 chrome moly steel alloy rated at 200,000 psi
• Precision heat-treated vertically in specialized racks for complete, uniform heat penetration
• Centerless ground after heat-treat for exceptional concentricity and straightness
• Thread rolled after heat-treatment for 10x better fatigue strength compared to pre-threaded fasteners
• Custom Age 625+ series material for superior performance under extreme conditions

Engineering Advantages:

• 12-point head design provides precise torque application and easy installation
• Undercut shorter studs equalize stretch characteristics for more consistent clamping force
• Studs install finger-tight and stretch only on vertical axis when torqued, eliminating torsional stress
• Included hardened, parallel-ground washers ensure even load distribution
• Precision tolerances allow cylinder heads and gaskets to align perfectly during assembly

Why Choose Studs Over Bolts:

Head studs provide superior clamping accuracy compared to bolts because they aren't subjected to twisting forces during installation. This results in more consistent torque readings and reduced risk of head gasket failure. Studs also simplify engine assembly, particularly for racing applications requiring frequent servicing.

Each ARP stud is marked with the ARP logo as assurance of quality. This kit includes all necessary studs, 12-point nuts, and hardened washers for a complete installation. Remember to re-torque after initial engine break-in to compensate for head gasket compression.
