Bob,

You got it.  Most of my studs had plenty of threads to double nut but none had
enough to tripple up or more.  However, I do agree with John that more is
always better when you can.  I usually remove head studs whenever I pull a
head even if I don't need to in order to get the head off.  There is usually
some gasket removal required that is harder to do with studs in place.  So you
might as well take them out before you remove the head.  It makes the head
removal job easier.  If a few good hits on the 2x4 doesn't work then the rope
idea is good also, I have heard of this before but never had to use it.  The
wood and big hammer has always done it for me and its pretty simple.
