<VV> Repair of head stud holes

[Tom Gould]

While reinstalling the heads one of the .006 studs  backed out. Clarks sells Heli-coil and Time-Sert inserts. I've used heli-coil type inserts on other bolt holes but this is the first time I've had to repair a head stud hole. It's on #2, next to oil cooler,  so I may be able to do it w/o pulling the engine.  Any input (pros,cons, suggestions) will be greatly appreciated.
