With all the work required to replace a head stud, you will quickly see that replacing all of the lower Dilivar studs with regular steel. Or, make a good upgrade and go for the Supertec studs. Once you have it apart, the heads should be rebuilt as well, This will cure and prevent most of all other issues with the engine for many years to come.

Other things that add to the while you are in there list:

Sensors. All should be replaced while engine is out.
Clutch, while you are in there....at least a new disc.
seals on trans and staft fork upgrade
clutch slave

This list will get very long!!!
