ARP head bolt question.

Can ARP head bolts be re-used? And if so. Does the torque specs or sequence change when re-using them? Thanks!

You can reuse them. Torque specs and sequence is the same, I would get some arp molly lube for torquing.

If using ARP headbolts:

Apply the moly lube that came with the ARP bolts to the threads, as well as under the head of the bolt and both sides of the washer. Only a light coating is needed. If you don't have the included moly lube, put some motor oil on the threads.

Torque all 15mm bolts to 30lbft in sequence.

Do a second pass at 50lbft, and finally a 3rd at 70lbft.

Finally install the 5 smaller ARP bolts and torque them to 22lbft.

I think TSP, amongst others, has the lube.
