1) they are reusable, saving you lots of money depending on how often you need to need or choose to remove the cylinder heads. in the long run they're cheaper than bolts.
2) they take the wear off of the aluminum block threads. I work with aluminum every day, and threads get boogered up incredibly easily, especially if they are not thoroughly cleaned and / or they are used repeatedly.
3) you get a more accurate clamp load as you approach the torque value since your torque is not being used to overcome friction under the head of the bolt AND between the bolt and block threads. the only area of friction contact in the studded scenario is under the head of the nut.
