I have stud mounted rocker arms, and I am about to tighten them down, however, each arm is at a different thread count from the top... does it matter if I torque them down to the same but have them at different elevations or should I tighten them down to the same level and throw some thread lock on them? The chiltons manual 1979-88 mustang/caprice says to tighten them to 18-25 ft/lbs but show using the falcrum attaching bolt, falcrum and rocker arm (which are not parts of the new rockers... all there is - a "washer" similar to the falcrum in position, the stud mounted threads, the rocker arm, and a nut on top of it...
Anyway, hope this wonderfully precise description helps!
