Default Torque specs for ARP studs

I tried the search several times, it keeps timing out. What are the torque specs for the ARP LS1 12 pt. head studs?

I also need the specs for the arp main studs.

Thanks!

For the head studs...

I used that as a guide but instead used the 20/40/70ft/lb sequence instead of 20/40/65.

MAKE SURE you use their ARP moly lube to get the correct tq readings. You should tq to spec, wait an hour, recheck the tq, let it sit overnight and check again. That's how I've done it and never had problems.

That is what I used as well with ARP lube. If oil is used instead, the figures can go up by 10.
