Buying tips

When choosing header bolts, consider material (stainless steel resists rust but can gall; use anti-seize), head type (12-point allows higher torque, hex is more common), and whether you need locking features for high-vibration engines. Stud kits simplify installation but cost more. Always check thread size and length for your specific vehicle.
