Carroll,

After sending my response to the list, I realized that I only answered some
of your questions.  If you have other questions, don't hesistate to ask.
BTW, how far into the job are you.  Are you doing it at home or are you
working with a shop?  You will need to remove the head, cylinders, and
pistons to get to those studs.  I'd recommend you open up both sides of the
engine as well, because you probably have rotten studs throughout.  You
might as well do a complete rebuild while you are in there.  How do the
heads look?

Regards,
Bill
