Manifold nuts

[Tyson Sherman <tsherman@tecinfo.com>]

I'm having a terrible time removing one of the manifold nuts
on my 73 Midget engine.  The nut is broken and will turn
freely and there isn't much stud to grab onto.   Any tips for
removing such an item? (I'm new to some of these Grapes
of Wrath tricks).  As you can guess, it's rusted solid.  The intake
ports on the head don't look too pretty either.  How can I tell
if the head is even reuseable?
Thanks,
