Printing on paper with preprinted heading

We are printing our official financial statements on paper with a preprinted heading. I therefore want the report to start 6-7 lines lower than the margin so it does not print upon the preprinted heading. If I edit header2.inc and put in 6-7 new blank lines in before the "Logo" that works fine. But it also makes the printing of the invoices start lower, which is not what we want. I can make a copy of header2.inc with the extra blank lines and call i e.g. header3.inc, bit how how do I tell FA to use header3.inc for the financial reports?
