The appearnce of the headers should be a function of your Normal style. To
change that, use the menu to choose FormatStyles

In the dialog that comes up, choose the Normal style, then click on the
modify button. Choose a smaller font and OK your way back out to the
spreadsheet

Hope this fixes your issue
