To edit Left4Dead, you need notepad++:
http://bit.ly/hzJvsh 

Next, Ctrl+F and look for the top lines, then edit them to look like the bottom ones.

Lines needed to edit:
$baseTexture "models\survivors\TeenAngst/zoey_color"
$basetexture "models\survivors\TeenAngst/zoey_head"
$compress "models\survivors\TeenAngst/zoey_head_compress"
$stretch "models\survivors\TeenAngst/zoey_head_compress"

Make them:
$baseTexture "models\survivors\TeenAngst/coey_color"
$basetexture "models\survivors\TeenAngst/coey_head"
$compress "models\survivors\TeenAngst/coey_head_compress"
$stretch "models\survivors\TeenAngst/coey_head_compress"

Note: Edit -ALL- lines that end with the first second (zoey_color; zoey_head; zoey_head_compress" not just the first/second ones.

Simple enough... so enjoy. :)
