How to add a custom Header for Genesis Theme Framework?

I have been using Genesis theme for sometime now. I also use Thesis theme which is also good. I wanted to add my own header for this blog. Reason was that I disable adsense when I am logged in or for any logged in user to avoid accidental clicks to Adsense Ads. Recently I added an Adsense Ad to the header widget but could not disable that as I cannot execute conditional PHP tags to the widgets (Plugins are available for this, but I did not want to use it).

I use a child theme for my Genesis theme installation so I added this code to the functions.php file of that child theme.

<div class="wrap">
	<div><h1 id="title"><a href="http://kish.in/" title="Kishore">Kishore</a></h1><p>Limits Undefined</p></div><!-- end #title-area -->
	<div class="widget-area"><div class="widget widget_text"><div class="widget-wrap">			<div class="textwidget"><div>

		<!-- Adsense Code here - runs only for users who are not logged in -->

		</div></div>
		</div></div>
</div><!-- end .widget_area --></div>

I had initially tried to do this using a plugin, but did not work for me.
