Idealy you should always replace the head bolt. most cases it is mandatory. check your specs. if the tightening sequence finishes with a 1/4 turn or some non foot pound reference then the head bolt must be replaced.
initially you tighten all bost to 28 newton metres then you angle tighten by 90 degrees leave for 5 mins and angle tighten by another 90 degrees this information was supplied to me by a trained rover mechanic i did it on my metro 1.1 on a j reg and it was fine
Pretty expensive (from a garage). Most people scrap their cars after a head gasket has blown, or get a new engine.
Changing head bolts is never a necessity, unless you have an issue with bolts breaking etc.
11 nm then 2 x 180 degree turns
40NM initially on all head bolts Then... 60 degrees on all Then another 60 degrees on all Then the M12x140mm bolts are a further 20 degrees
Depends on what engine you are working on.
