1st off the main use of a torque plate is to insure the cylinders keep the roundness during honing and/or block filling...ETC....
i do not see where head studs would have any bearing on the block what-so-ever in reference to the question you ask......a BIG mistake many do make when using studs is that they screw the stud very tight into the block with a allen wrench...when this happens it really takes away from the compression advantage a stud gives...the proper way to install a stud is to srew the stud into the block hand tight preferly so when you put the bolt on it has has a very strong compression factor as the high tensil steel pulls the thread (s) together from the block side and the head side.. as i mentioned above if someone tightens down on the studs until they bottom out with an allen wrench until they cannot turn anymore..it then acts the same as a regular head bolt..and no better then a head bolt at that point
just be sure to put proper sealer on the threads entering the block ( many opinions here i personally use mega black gasket sealer with no leaks) when placing the head on the block follow the Tq Pattern the head calls for..also be sure to use 30 wt oil or the recommended ARP lube between the washer and the nut so you get a nice even pull which ensures your TQ reading..
i know i added a little more info than you ask for but rather give it to you just in case you did not know.
