All,
I cannot sing the praises enough of putting in a flex flange between the
header and the rest of the exhaust system. I had one on my 67 2000 and drove
the car hard for 13,000 miles with nary a rattle. I just recently took the
header off and it is not cracked and the flange will be cleaned and
re-attached when I put the car back together.
It allows your exhaust system to "flex" and will help in keeping your
header/manifold from cracking and causing P.O. muffler shop headaches in the
first place.
If you have the exhaust system out of the car, put one of these things in.

I had the same problem. We wound up using a detached hacksaw blade, which
worked pretty well for a one time deal.
The stock headers are a lot cheaper than the stock manifolds and easy to
come by.

P.S. Gordon Glasgow had a great suggestion, which I haven't tried yet. You
are going to have a few inches that you'll need to have a muffler shop
patch. Gordon recommended having them use flex pipe which will allow the
exhaust system to be adequately anchored without putting so much stress on
the header. Gordon, correct me if I translated that badly.
