your not having a lot of luck there matey
...another option for you...the studs that have broken off close to the surface cound be removed with an "easy out" its like a tapered, left handed screw.drill a small pilot hole and wind the "easy out" in anticlockwise,when it tightens all being well it will unscrew the stud and not damage the threads in the cylinder head


One, is never going to be enough.....
