ARP 147-3901 Head Bolt Kit

If you value exceptional quality in your fasteners, then these head bolts are for you. These bolts came very well protected in a thin coating of oil, with the threaded portions covered in individual plastic sleeves. I like that these bolts also do not require a final torque angle, but call for a final torque of 100 lb-ft (the smaller head bolts get a lower torque). Instructions including recommended torque sequence are included. I recently completed purchasing a large variety of OEM fasteners for an engine swap project, but after experiencing these ARP bolts, if I had to do it over again I might have spec'd out ARP fasteners for everything else as well.

They do the job and then some !!

Worked like a charm. The best quality, ARP does not disappoint.
