Most of us never check the cylinder head torque....as we have never seen any of them come loose - or a head gasket fail.
If you want to check the torque...you can't just stick a wrench on them and torque, as two of the nuts are exposed to the elements and get corroded. You have to take them off one at a time, clean the threads, apply some anti seize (or oil when under the head cap), then torque it down.....repeat until you have done all 4, and then check the two of them are are located under the intake and exhaust ports.
