S/S Header Stud Kit - 3/8in x 1.670in OAL (12)

The ARP S/S Header Stud Kit – 3/8in x 1.670in OAL (12) is a premium-grade fastener set engineered for small block Chevy engine builders and performance enthusiasts who demand reliability under extreme cylinder head clamping loads. This 12-piece stainless steel header stud kit provides the strength and corrosion resistance required for both naturally aspirated and forced-induction engine applications where standard fasteners fall short.

Each header stud measures 3/8 inch in diameter with a 1.670-inch overall length, optimized for small block Chevy intake and exhaust manifold mounting. The polished stainless steel construction resists corrosion and thermal oxidation while maintaining tensile strength across wide temperature ranges. The 12-point nut design ensures consistent clamping force and reduces the risk of rounding or stripping during installation and removal cycles. ARP's proven thread geometry and quality control standards deliver the clamping accuracy that high-performance engine builds require.

This kit is essential for engine builders, restoration specialists, and performance tuners working on small block Chevy platforms who recognize that header fastener failure can compromise combustion sealing and lead to exhaust leaks, power loss, and thermal management problems. Whether assembling a street engine, race platform, or long-term restoration project, this stainless steel header stud set eliminates the guesswork of sourcing individual fasteners and ensures consistency across all mounting points.

ARP header studs are recognized throughout the automotive performance industry for superior metallurgy and dimensional accuracy. The stainless construction of this kit offers a practical advantage over standard fasteners in corrosive environments and high-heat applications common to engine bay use.
