ARP 154-4005 Pro Series Cylinder Head Stud Kit for Ford 289-302 with 351W Heads

The ARP 154-4005 Pro Series Cylinder Head Stud Kit is engineered for Ford 289-302 small block engines running 351W cylinder heads. This precision-manufactured stud kit features 7/16-14 cylinder block threads and is compatible with M-6049-J302, SVO high port M-6049-L302, and Edelbrock aluminum GT-40 style heads with insert "T" 1/2" to 7/16" washers. These head studs are essential for maintaining optimal cylinder head-to-block sealing in high-performance applications employing high compression pistons, turbochargers, nitrous oxide, or superchargers.

Premium Construction and Manufacturing Process:

• Constructed from premium grade 8740 chromoly alloy, rated superior to aircraft quality materials
• Precision heat-treated to 200,000 psi tensile strength for exceptional durability
• Centerless ground after heat-treat through approximately ten precise cuts for maximum concentricity and straightness
• Thread rolled after heat-treat, providing 1000% better fatigue strength compared to pre-heat-treat threading
• Specially undercut shorter studs to equalize stretch and provide consistent clamping force
• Includes hex nuts for secure installation

Performance Benefits:

• Exacting tolerances allow gaskets and cylinder heads to glide into position with perfect alignment
• Consistent clamping force compensates for head gasket compression during installation
• Prevents blown head gaskets and ensures optimum sealing under extreme conditions
• Superior strength and reliability for high-performance and racing applications

ARP's meticulous manufacturing process and premium materials make these head studs the choice of leading racers and engine builders who demand the best in cylinder head fastening technology.
