I'm using the Graphene theme (latest version) with a child theme on my client's site http://www.walkinghorseowners.com. I've looked through the other posts related to this topic and have done all the steps I've seen to change the header image size.
I've changed the child theme's CSS #header height and #header_img_link height, then adding the following to the child theme's functions.php:
<?php
function graphene_custom_header_width(){
return 960;
}
function graphene_custom_header_height(){
return 140;
}
add_filter('graphene_header_image_width', 'graphene_custom_header_width');
add_filter('graphene_header_image_height', 'graphene_custom_header_height');
?>

entire header.php: http://pastebin.com/Mvi6Y7hy
Currently the header image appears correctly in the Custom Header preview, but the top of the image is cut off on the live site.

Can anyone tell me what I've done incorrectly?
