When it comes to fasteners, you can't beat ARP.
We use ARP fasteners throughout our engine builds.
This is a complete kit of 10 each ARP head studs, washers, and twelve point nuts. ARP assembly lube is also included.
Torque these studs to 70ftlbs using ARP assembly lube. Be sure to follow the 2ZZ-GE torque sequence as found in the service manual of our Tech Wiki
