When Should I Retorque the Cylinder Head

For the longest time I was having a hard time wrapping my head around retorquing or worse, reusing wasted bolts.
Why would you do that?? Then it became clear retorquing a waisted bolt is a good thing whereas retorquing a wasted bolt is not.
You probably don't want to use a wasted bolt in a waisted application, but you could perhaps use a waisted bolt in a wasted application.
Or maybe not....Regardless, it is so much clearer now........
Carry on.......
...it's all wasted on you then?
 
The torquing method should be no different for waisted bolts.
The only difference with them is they are slightly "springier" so they will stretch, elastically, a bit more on a hot engine meaning they won't crush the alloy of the cylinder head.
