Rocker stud torque value?

[trotterlg]

I have ARP adjustable studs in an aluminum head, I cannot find any place that lists the torque value. I find the torque value for the nuts that hold the stock rocker arms on but not the torque value for the studs into the head.

Probably safe to use the same torque specs as the factory roller fulcrum rocker bolts.

And that would be??????????????????

There was a thread on that topic a day or two ago

No, the 18 ft pounds is for the nut on top of the stud, after much research I find the stud into the aluminum head is 47 ft pounds. Not easy to find, this is for the 96 and up heads. Larry

This is a 3.1 gen 3 head. The torque in most tables is for the bolt on top of the stud, what I need is the torque on the stud into the head. I have now found 45 to 50 foot pounds in several places, it also jives with the torque for the studs into an aluminum head of a 3.8 which uses the same size and thread pitch. This is also about what I had to pull to get them out, seems like about 60 to 70 foot pounds to break them loose. Larry

I know you are trying, but I know that is not right, the nut on top cannot be tighter than the stud is into the head, unless you find some way to hold the stud so you can tighten the bolt on top tighter than the stud is in the head. I am happy with the 47 foot pounds. Larry

I can see it being fine if locktite were used

If it isn't right, it would be ok to use that value as I used it many times with medium strength loctite.
