head games

[Turbo Dog]

Well time has come to retire my 92 SE-R.  The body rot and clear coat failure are the PITA problems.  We are buying a new second car and I will take over my wifes 95 SE-R and make it a turbo. When I do the 95, I have a low mile block I'm swapping in.
  Problem - a kid snapped a cam retaining bolt off in the head. SHould I try to get it extracted, or use an old head and get it reshimmed?
