[BFix] rusted/broken exhaust manifold bolts

[Shehatesmybronco at aol.com]

Ok I need to know some of the tricks to getting the rusted and broken bolts  
out of the heads from my manifolds.  The headers on my 74 (302)are rusted  
through in a couple of places and I started trying pull them and they started  
breaking off so I stopped.  I don't want to have to pull my motor or my  heads 
to correct these broken studs and bolts.  A guy at work says to weld  a nut on 
the stud (if it's got enough to weld to) with an arc welder.  He  said it gets 
it hot enough to expand but not hot enough to lose  it's strength.  When it 
cools he said to use PB blaster or some type  of penetrating oil on it and let 
it sit over night and they are fairly easy  to get out. Has anyone ever tried 
this and does it work?  Is there and  easier way?  I have a broken stud on my 
78 also and I really don't want to  mess with the 351M.  Any help I could get 
would be greatly  appreciated.
