Product Details

The ARP 180-1401 header stud kit is engineered specifically for Oldsmobile big block and small block V8 engines, providing superior clamping force and reliability for exhaust header installation. This premium-grade fastener kit ensures leak-free header mounting and prevents the loosening common with standard bolts under extreme heat and vibration.

Key Features:

  • Custom 450 chrome moly steel construction with black oxide finish for corrosion and heat resistance
  • Rated at 170,000 psi tensile strength—substantially stronger than Grade 8 hardware
  • 12-point nuts allow easy socket access in tight spaces near exhaust pipes
  • Unique nut-starter nose on each stud prevents cross-threading during installation
  • Complete kit includes 14 studs, premium-quality washers, and 12-point nuts
  • Designed for both street and racing applications

ARP header studs provide a more secure and reliable mounting solution than conventional bolts, with the studs remaining permanently installed in the cylinder head while nuts are easily removed for header service. The black oxide finish protects against corrosion while the chrome moly material withstands extreme exhaust temperatures without losing strength.
