I remember Ford having a torque spec on their aluminum head engines in the 80's
that read " Tighten the head bolt to XX ft lbs, then turn the bolt an
additional 1/4 turn."

For those that don't get it, a few did, once you feel the torque drop the bolt
has already reached its limit and is broken.
Once you see the SWR go up it is most likely too late.

Well crap, that explains a lot, it is just "before" they snap!
... Just like tightening head bolts on a V8. You torque the bolts until
just before you fill them give and they snap.
