They are stretch bolts so should be replaced but many people don't (including me) and have got away with it (including me!!)

They're not stretch bolts and are reusable.

There may be a maximum length specified somewhere in elearn though.

They are 100% stretch bolts, the tightening sequence given in the workshop manual is ONLY used for stretch bolts.
Tightening sequence is nothing to do with stretch bolts, it's to stop the head from warping. They are not stretch bolts.

any bolt that is subject to heat as well as torque, stretch thus data to check length and for the sake of 30 odd quid dont skimp in my eyes........

Well duh, but that doesn't make them stretch bolts. As I've already said I think there is a maximum length specified in one of the workshop manuals but I've never need to replace any with new ones. So you're just wasting your money IMO.

When it comes to head bolts, I think the best advice anyone can give is to make sure the threads in the block are free running, ie free from corrosion and other debris. You can clear them out using an appropriately sized tap or by cutting grooves lengthwise into an old head bolt.

With bolts that go into an alloy block it's always wise to use some alloy paste on the bolts but I this case copper grease wouldn't go amiss.
