They aren't really supported any more and there can be problems using them,
but you can still do so either by reviving the old Mail Merge Helper
(Tools|Customize, select category All Commands, locate Mail Merge Helper in
the list of commands, and drag it to a toolbar, e.g. the Mail Merge
toolbar.) or using ActiveDocument.MailMerge.OpenHeaderSource in VBA.

I have a mail merge Word doc that I created in Word 97 now using Word 2003.
I
can't figure out how to change what header file I want to point too. The
header file is a word doc that is tab and carriage return delimited. It
appears that possibly header files are not used any more?
