Basically if you compare the ARP head studs, to the OEM bolt they should just be a little longer than 100mm in length, (I would think 110mm for the nut and washer).Stock bolts are 100mm as well. So if the studs are a little longer than they are suppose to check the thread depth you should have atleast 25mm or better of depth at both ends in order for it to work.
You ordered studs, there is also a head bolt kit as well. I don't know if that is what is causing the confusion.
