Installation Recommendation
Whenever replacing cylinder head gaskets, new cylinder head fasteners are highly recommended. Reusing old torque-to-yield head bolts can compromise clamping force and reduce gasket life.
For the best long-term reliability, we recommend upgrading to SWAG Performance Parts Premium Cylinder Head Studs or ARP Head Studs. Both provide superior clamping force compared to factory head bolts, helping to keep the cylinder heads securely sealed under high boost, heavy towing, and demanding performance applications.
Recommended Upgrades:
- SWAG Performance Parts Premium Cylinder Head Stud Kit
- ARP High-Performance Cylinder Head Stud Kit
Installing quality head studs during your head gasket replacement can significantly reduce the likelihood of future gasket failures and improve overall engine durability.
