how do you figure this exactly? that cylinder is on 4 studs..2 of which are doweled.. diagonal tightening brings the jug down as square as possible. and the dowels keep the cylinder aligned properly. once that cylinder is snugged down it's not moving because one nut is a shade tighter than the others..Each one should be tensioned diagonally at 18ft lb, I dont believe you should guess the tightening as one can get the barrell cocked at a slight angle, if you are using a thicker than OEM gasket.
I too do not use any type of torque wrench. I tighten them till they are snug, then another good pull on the 12mm wrench till there good-n-tight- and check them after heat cycles. I can guarentee they are over 18ft lbs but have never had a base gasket issue!

well thats news to me... i've installed hundreds of cylinders.. never had an issueI have witnessed lugs broken off the bottom of jugs caused by uneven tightening.
Expansion/contraction will choose the one to crack off, especially if it is too tight.
