What does upgrading head studs do?
The design behind a head stud is to have a fastener that does not stretch. This is done by using a high tensile strength alloy and a stud rather than a bolt. The stud allows for a fine thread nut on the top which will result in a more precise torque of the head.

What is better head bolts or studs?
In other words, head studs are better suited for high-performance vehicles with greater power requirements, while head bolts are more practical for personal, everyday automobiles. Therefore, it would be inaccurate to conclude that one type of fastener is categorically superior to the other.
