>From experience I would agree but with old style cars you don't need to
replace them every time. With older cars you just get a touque to tighten
the studs too, but with new ones you also get an angle. So you tighten the
bolt down to a certain torque and the turn it through the angle specified.
The streches the studs and reduces the risk of a blown head gasguet. One
thing it is worth mentioning is the nuts you use, I used brand new ordinery
nuts and found that the head kepped on blowing, I then swapped to second
hand mini nuts and haven't had a problem since. So make sure that your
replacement part are up to the job.
