Remove Head Block From Page

You can either unset head block entirely, or just remove the script files. What you need to do is to create an observer on

controller_action_layout_render_before
event, and create this observer function:
public function removeHead()
{
 if (Mage::app()->getRequest()->getModuleName() == "lazyload") { //put your module/controller/action name here so you don't remove head for every single page
  $layout = Mage::getSingleton('core/layout');
  $layout->unsetBlock('head');

  /* second level of destruction - because this block has two lives .. like a final queen in an arcade */

  $head = $layout->getBlock('root')->getChild('head');
  if (is_object($head)) {
   $head->setData('items',array());
   $layout->getBlock('root')->setChild('head',$head);
  }

  /* third level of destruction - if the bitch respawns */
  //$layout->getBlock('root')->setChild('head', new Mage_Core_Block_Template);
 }
}
