ARP Head Stud Torque specs??

For what it's worth, with my ARP head stud kit, I went with 80ft.lbs. They actually made the bolt. Seemed like the smart thing to do.

58,000km later and no problems...

How did your gear box feel about it? :mrgreen:

I destroyed forth in a five speed box, but I think this is unrelated?? Or I don't get your bad joke? :lol:

Thanks mate.

Appreciate it.

My brother and i are the Engine builder (Loosest possible definition of the term :oops:

)

We have the engine in but i believe lil bro only torqued them upto stock figures.

Might be worth taking the cam cover off and retorquing them upto 80ftlbs.
We used the Ultra Torque assembly lube.

Would it be an issue to torque them now to 80ftlbs after then engine has heat cycled?
Ie- would the lube now be not working as it should from the heat?

Again thanks
