- Cat and tow proof method: The nuts will have 'set', and applying the standard tightening torque will probably not shift them. Follow the normal tightening sequence, and for each nut in turn - back of

- Reverse order IS correct but one at a time. Un-Do approx. 1/4 to 1/2 turn Retorquing the head studs is going to result in an increase in clamping of the head to the block. The effect is an extension

- So, I've got nearly 1000 miles on my newly rebuilt engine in my MK II MGA and I figure it's time to re-torque the head. So, whattaya think, slowly loosen all of them in reverse order, then re-torque,

- I had always thought when retorquing that you proceed one at a time, loosening each nut slightly, then retorquing to the proper spec. That's how I've done it for 30 years and it always worked for me.

- I remember seeing it on the list before. Maybe something about breaking loose some friction of the bolts so that you get accurate reading on the torque wrench. I don't know, I may be making that up.

- In all seriousness I would break them loose but not actually loosen them, maybe an 1/8th of a turn at most.

- The way I learned it, after the engine heated up and cooled down, the head gasket would compress a bit but not evenly. So the idea of the re-torque was to even out the clamping force again. Some nuts
