Guido you may want to look at the OP again. This motor has not been recently worked on but has a slight oil leak which he wants to try to eliminate by torquing the head bolts. Though it is not likely to work, I believe that he has very little to loose so why not? I think that most of us here agree that after a few years of working and heat and cool cycles that nuts and bolts in use pretty much anywhere on pretty much any machine that heats up with use will tend to get a little stuck or, if you will, held by more than just the normal stretch of the bolt. So when you combine the friction added to the stretch, it is highly unlikely that any bolt will break loose and move one degree of clockwise rotation. Whereas if bony first eliminates the added friction with just a 3-4 degreee counterclockwise movement, and then goes to torque spec. clockwise, he will probably gain a little here and there and possibly even stop the leak.
