I already know the answer. I was just posting this for someone else who was looking.
I responded to the post with a question, then could not answer back.

Answer 2

Torque is a measurement of energy expended in the Twist. A gage measures torque, or in the absence of such a gage a release mechanism is employed. Such as in the term Break Away. Torque values are based upon the manufacturers hardware. Certain Metals and Alloys have precise breaking points. In tightening a head the bolts, studs and threads all play a part. Changing the values of any one or all effect the purpose of the design.
Torque in this case allows the stretch of the bolt within the limits of the breaking point.
Replacing steel bolts with Tungsten will enable a higher torque value to be employed and therefore allow a piston modification that results in a higher compression rating for the use of higher grade fuels resulting in more horsepower. A stock engine of 300 horse power can be modified for 500 horse power net torque to transmission and drive train. The advantage of this is that you can conceal the fact that your engine has more power than the Stock Engine.
Do not under value torque required in the assembly of any internal combustion engine.
