As I`ve taken a few 5 cylinder engine apart and now have a quite a few sets of used head bolts.
One set I`ve got was only on a engine for 300 miles.
I`ve compared the length of all the head bolts and they are all the same length.
I now they are stretch bolts or are they ??? or just a marketing thing to get people to buy new bolts every time the head is removed ???
