ARP 205-4201 Holden 308 CID 12-Point Head Stud Kit

The ARP 205-4201 head stud kit is engineered specifically for Holden 308 cubic inch engines equipped with 10-bolt cylinder head configurations. This professional-grade fastener kit features 12-point head studs manufactured from ARP's premium 8740 chromoly steel material, providing superior clamping force and reliability compared to factory head bolts.

Key Features:

• Designed for Holden 308 CID engines with 10-bolt head pattern
• 12-point head design allows for precise torque application and easier installation in tight spaces
• Manufactured from heat-treated 8740 chromoly steel for exceptional strength and durability
• 200,000 PSI tensile strength rating ensures reliable cylinder head clamping under high performance conditions
• Parallel ground threads provide more accurate and consistent torque readings
• Includes premium ARP thread lubricant for proper installation

ARP head studs are the preferred choice for performance and racing applications where cylinder head gasket sealing is critical. The stud design eliminates the twisting motion that occurs during bolt installation, resulting in more accurate and consistent clamping loads across the head gasket surface. This kit provides the ultimate insurance against head gasket failure in high compression, turbocharged, supercharged, or nitrous-equipped engines.
