DOn't obsess over numbers. Torque of fasteners is determined by the strength of the material of the fastener, the thread profile, number of threads, etc. Torque specs will sometimes be less than the yield strength of the fastener based on design parameter, but never greater. The engineers designing the product determine the desired torque based on load, whether in shear or compression, etc. number of fasteners, etc.
Example: Look for the torque spec for a 2n water outlet housing. Adding a few ft/lbs torque or degrees of angle "jus cuz it holding the heads, turbo, rods mains" etc is not the answer. It stretches the threads and the fitment will loosen prematurely.
Put the 5/16-18 bolts with lubed threads in and torque it to 20-25. It will hold.
You're not replacing the pressure plate on a 475hp 1750 ft/lb torque CAT or 855 Cummins motor.
Those get new CAT bolts, washers and torqued using the template method.
