// Actions
add_action('wp_head','wp_enqueue_scripts',1);
add_action('wp_head','feed_links_extra',3);
add_action('wp_head','rsd_link');
add_action('wp_head','wlwmanifest_link');
add_action('wp_head','index_rel_link');
add_action('wp_head','parent_post_rel_link',10, 0 );
add_action('wp_head','start_post_rel_link',10, 0 );
add_action('wp_head','adjacent_posts_rel_link', 10, 0 );
add_action('wp_head','locale_stylesheet');
add_action('wp_head','noindex',1);
add_action('wp_head','wp_print_styles',8);
add_action('wp_head','wp_print_head_scripts',9);
add_action('wp_head','wp_generator');
add_action('wp_head','rel_canonical');

And to exclude them (I left the real useful ones):

remove_action('wp_head','wp_enqueue_scripts');
remove_action('wp_head','feed_links_extra');
remove_action('wp_head','rsd_link');
remove_action('wp_head','wlwmanifest_link');
remove_action('wp_head','index_rel_link');
remove_action('wp_head','parent_post_rel_link');
//remove_action('wp_head','start_post_rel_link');
remove_action('wp_head','adjacent_posts_rel_link');
//remove_action('wp_head','locale_stylesheet');
remove_action('wp_head','noindex');
//remove_action('wp_head','wp_print_styles');
//remove_action('wp_head','wp_print_head_scripts');
remove_action('wp_head','wp_generator');
remove_action('wp_head','rel_canonical');
