supra 2JZ head stud kit from ARP?

[NLXTACY]

What was the break-in period? I just had these put on my truck after a head rebuild.

500 miles supposed to re-torque

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'm just curious how much are the stock studs that people are saying are expensive.

If you aren’t planning any engine modifications like turbo or SC, they aren’t needed. If you planning on it then also plan on Cometic gasket.

I'm assuming that will be included in the new kit

I kid, but at this point would not be surprised

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
