Header Stud Kit - 12pt. 3/8 x 1.670 OAL (12)

The ARP Header Stud Kit – 12pt. 3/8 x 1.670 OAL (12) is a specialized fastener set designed for Small Block Chevy engine builds. This kit is ideal for builders and engine shops focused on street performance, racing, or restoration work, providing the essential components needed to secure headers effectively.

Manufactured from high-strength chromoly steel and finished with a black oxide coating, these studs offer superior strength and corrosion resistance. Each stud measures 3/8 inch in diameter and has an overall length of 1.670 inches, specifically designed to fit header flange hole patterns on Small Block Chevy cylinder heads. The 12-point nut design enhances grip and minimizes fastener rounding, making installation and removal easier in high-vibration environments.

Header studs provide a significant advantage over conventional bolts, as they remain fixed in the head while nuts are torqued, reducing the risk of stripping threaded holes. This kit is a must-have for anyone serious about building or restoring Small Block Chevy engines, ensuring reliability and performance under demanding conditions.
