Help, seeking a head

[David Templeton]

Hi all,

I tried to take the last head bolt out of the donor car after getting the
other 9 came out easily and it stripped. I made sure I used the right tool
but it spun and rounded the edges of the bolt and the tool.  So, I am in
another pickle, either someone suggest an "easy" method of getting the bolt
off to remove the head, even if I could get the bolt head taken off would be
good.

Or I need another donar head local to the Guelph area in southern Ontario
please.

Any help would be great, thanks
