500 miles supposed to re-torque

I keep seeing that across different forums, but ARP's site says the following:

Do I need to re-torque my head bolts or studs?

If you follow the ARP installation instructions, there should be no need to do a re-torque. However, it may be necessary under certain circumstances if the gasket manufacturer’s instructions require it, particularly if a fire ring has been installed. ARP recommends not doing a re-torque on a hot engine.

I called ARP three years ago when I installed the 1fz stud kit from Paradise Racing and they told me the same thing; “follow your gasket manufacturers instructions, re-torquing the studs is not necessary”. I asked the Mud community and, at that time, there were several members who had installed arp studs and never did a second torque.

I ended up rolling that cruiser 6 months later and that engine now sits quietly collecting dust in my garage so I never had a chance to put many miles on that heat gasket to see how well a single torque sequence would hold up.
 
I have about 25K on my 80 since the headgasket, and I installed ARP studs at that time. No retorque, no issues so far.
 
When I did my engine build 6ish years ago, the instruction from ARP and Cometic was to re-torque BECAUSE I was running both together.

To reiterate, at least 2 of them needed to be retightened to get them back into spec after 500ish miles. I would 100% do exactly the same.

I’m now at 80k+ on the rebuild and it’s my DD.

YMMV
