One is some of the multi-phase, stainless steels. These materials can be processed into the 265,000 psi , ultimate tensile range and still remain very ductile. Still that sounds like great insurance if you're talking about an expensive race motor. Manufacturers of most quality fasteners, designed for racing, will supply some tightening specifications, torque reference number or stretch data. You probably already know it is usually listed in foot pounds of torque.
Friction is an extremely challenging problem because it is so variable and difficult to control.
Many fastener manufactures recommend using the stretch method since the preload is closely controlled and independent of friction. The friction for a particular installation can change from one application of torque to the next. That is, when a bolt is torqued for the first time, the friction is usually at it's highest value. Each additional time the fastener is torqued and then loosened, the friction factor becomes smaller. Eventually, the friction levels out and remains constant for all following cycles.
