This will look greyed out, so you just need to double click in this area (in page layout view) to access and amend this.

I have set tabs, which are centred for both "Title" headings, just select each one to change the text.

However, if you choose to add addition pages and you wish them to be different from these you will have to insert section breaks and choose to unlink the headers from the previous header. Come back if that is your intention.
