You should create view with the "block" display. This block can be placed in any region using standard block/theme functionality. If you don't have "header" region, you can create your own. See this link for details. https://drupal.org/node/1088718
Maybe, i do not quite understand you question (actually, phrase "header node" confused me, you mean header area/region?). If you need to display view on the node page, you can use views_attach ot eva modules.
