Use the old ones as the ma engines dont use stretch bolts, trust me as ive done a head job!

ahh ima jst order some new ones tomorow, makes life alot easyer for the guy thats doing it plus i cant see them being too expensive, less hassell.

on the old cvh engines thy used stretch bolts i.e. they stretch when you tighten them up, and your supposed to replace them, but in the micra engine they dont stretch and dont need replacing.

hope this helps

What are Stretch Bolts ??

As I'm replacing my headgasket I thought they were something to do with using longer/stretchable bolts, as when head is skimmed, old bolts are no longer suitable.

Am I completely wrong ??

stretch bolts do what they say on the tin...stretch!
Did a renault headgasket before with them, it just means when you tighten the head bolts up you have to do to a certain torque then a certain amount of degrees turn.

Your headbolts will be fine on a micra mate.
