You need to change the values set in class_core.php

PHP Code:

/**#@+
* The maximum sizes for the "small" profile avatars
*/
define('FIXED_SIZE_AVATAR_WIDTH',  60);
define('FIXED_SIZE_AVATAR_HEIGHT', 80);
/**#@-*/ 


Then have all your users re add their avatars, and I think that will work. You can test it out on your own user to see if it does.
