    ok here goes. studs torque to 26+or-4 lbs ft. nuts 28+or-4 lbs ft. cant figure how to show a diagram so top row 11 3 7 1 9 5 bottom row 4 12 2 8 6 10 hope this helps. almost forgot put neverseize on the studs before you install in head and on turbo studs.

    Dont torque the studs in that tight. It makes them very hard to get out if they break.

    How do ya know what the number of the stud is that you’re tightening? You say tighten 11 first. Which one is 11?

    The numbers are the sequence you go by starting with 1.
