<VV> non-Corvair question...

The first step is to take every variation of an EZ-Out that you own and 
throw them as far as possible.  That way you won't be tempted to try to use 
them.  They might work on a brand new bolt that somebody gorilla-armed.  But 
when (not if) one breaks off in a rusty and stuck bolt/stud your problems 
have just begun.

You can try welding a nut on.  Let it cool completely.  If the nut twists 
off, try it again.  Rather than welding the nut (or if it doesn't work) heat 
the stud as hot as possible and let it cool completely.  Drill the center of 
the stud then re-drill with larger bits until all that remains is the 
threads.  Use left handed bits.  You might get lucky and have the remaining 
part of the stud unscrew.  Then carefully remove them with a tap.

Tip/rotate the engine so that the surface where the bolt has broken off is
face up. Coat the broken off bolt with a 50/50 pre-mix of acetone and ATF.
keep the broken off bolt wet for several hours. Drill a hole for an ez-out
or bolt-out and see if you can get it out.

I have also used a commercial product called Mouse Milk in a similar
manner. I actually don't think it is as effective as acetone/ATF but it
doesn't damage nearby paint or discolor the part which can happen with
acetone and ATF.
