How to remove calling ARCADE.css from header?

Hello,
I have "Store CSS as files" enables and have combined all the CSS files into one.
Now, when I removed all the css imports and calls from headerinclude and headerinclude_bottom template except the combined one, it's still being called as per the page source.

PHP Code:

<link rel="stylesheet" type="text/css" href="clientscript/vbulletin_css/style00025l/ARCADE.css" /></head>

(Just before closing head tag) 

How can I remove that to save an additional HTTP request?

Thanks in advance

[Hippy]

copy your arcade.css completely into vbulletin.css
Store CSS as files will then work.
add it just above .blockhead
