    Torque spec for studs that hold cam trays

    In the process of putting the head together I realized that I can't find any torque specs for these studs!

    They were removed when the machine shop did some work for me.

    Anyways, what is the correct torque spec and should add some kind of thread locker to them?

    Last but not least...where the hell do you guys get your torque spec info?!

      Here's what I do. Put the ratchet in your balled up hand (like a fist) with the extension/socket coming out between your middle and ring finger. Then get the nut as tight as you can that way. It usually works out to being somewhere around 25-30 in lbs I believe.

          I think you may have misunderstood. The studs were removed from the head when it was bead blasted. I'm trying to figure out what the torque spec is for the stud itself.

          If you're saying that I need to get the nut on the stud (going to need two in order to tighten it) then obviously I'll do it like you said :)

          Not sure we're on the same page but hopefully the the pic on realoem will help.

              There's isn't a torque spec for a head stud, no is thread locker needed. You each stud in until it bottoms out
              The car makes it possible, but the driver makes it happen.

                  You don't torque a stud, you torque the nut installed onto it. Thread in the studs by hand until they bottom out. Don't tighten them against the bottom of their hole.

                          Oh, my bad. Yea. Like Matt said, make sure they don't bottom out in their hole. If you try and just get them as even as possible, you should be good.

                              Get a bootleg copy of the TIS for torque specs BTW.
