I've just went through this with two blocks. I've tried a number of strategies.
Before anything, soak the studs in some type of rust buster a few times a day for as long as you can.
The mechanical process of getting the studs out was a two step process.
1) Heat the entire stud to cherry red with Oxy-Acetylene torch; especially the section close to the block. While cooling down, melt candle or bees wax at the base so it wicks down the threads. The theory is the heating (expanding) and the cooling (shrinking) breaks the bond of rust between the stud and the block.
2) After allowing it to cool down for a day, I've place an acetylene plumbers torch inside the holes for a water jackets and let that heat the bosses from the inside. I gently start to try to back out the studs with a stud puller of the studs near the torch. I move the torch down the line as I work.
This takes some experience to know when to use more force or to let the stud be for it's going to break. Sometimes you just get unlucky.
Be forewarned, one block took me 15 hours to remove all the studs.
