<VV> Stuck valve cover bolt.

[Ignacio Valdes]

Hi, The head broke off on this valve cover bolt. I've tried multiple ways
of getting it out drilling, weld a nut on,easy outs, without success.
Professional local shops in Houston Texas I tried are passing on this
because too old, still on the car, don't want to mess with it, etc.  Any
advice is appreciated.

Also, what is the preferred tool for holding the rocker stud from spinning
when you take the rocker arm nut off?
