We are renovating our house and want to move the header in a 6' opening on

When you say "move the header", I'm assuming you intend to have a
smooth ceiling rather than a section of wall.

Is the header part of a bearing wall?
If it is * not * a bearing wall, the header can be removed without
major work.
It it is part of a bearing wall, there is a lot of collateral
structural work to be considered.
