[FC] more Tips For Removing Exhaust Studs?

[corvanatics@corvair.org]

sometimes when stud is broken flush i get them out by cutting a slot in it 
with a dremel to fit a good size screwdriver. then i heat it as hot as i can and 
cool it suddenly by dipping in water then heating it red again and unscrewing 
it with screw driver. if i get real brave i have just blown most of a stud 
out of the hole with cutting torch and picked the rest out with a small chisel. 
then of course running a tap.  my best save so far was a block with a broken 
stud in a blind hole(upper head stud first one on the dist side)  i just 
quickly blew it out with torch.  it did not hurt the block and holds god tourqe just 
fine..boy was i happy to save that WB block!   (64 fc 110pg)
