Also the header.php file contains only the text to be placed in the header, not the code that does the placement. This is why the constant names (in capitals still appear). The code that you want to delete is in tpl_header.php.
However, you should not delete references to HEADER_ALT_TEXT or anything with ALT in as these are the alternative text that is displayed when people have images turned off (e.g. when using screen readers) and you code will not validate without them.
Also in the current version of Zen Cart, simply removing the text in red below is enough to prevent the tag line from being displayed, or taking up any space.[QUOTE] define('HEADER_SALES_TEXT', '[COLOR="Red"]
