[Healeys] retorquing cylinder head nuts

[richard mayor]

I back off the nut about 1/8th of a turn before re-torquing.

Yes you must loosen a nut/bolt before torquing.  It makes more torque to break the nut/bolt loose than it does to keep it turning.

Listers,

When retorquing cylinder head, should one loosen the nut being retorqued first? Not completely loose, but I would think that a nut could be under torqued, but would take more than the spec torque to break it loose.
