You may want to give serious consideration to having the machine shop remove the studs. They can easily break off, especially the ones that screw into a water jacket. Extracting a broken stud can be tedious, time consuming and stressful work. Good advice about the different stud threads. A couple of hours of machine shop time to remove the studs may be a bargain in the long run. However, if cost is a factor then the stud remover O-D suggested would be the one to use. Also, apply a good penetrating oil and allow it to soak in for a couple of days. Kroil is a good product for this. Some heat and impact vibration will also help, but this takes experience and care. Damaged threads will have to be repaired with Helicoil or similar inserts Good luck.
