Please could somebody invent a head type extractor for the head.big file???

When i try to import new faces i have to import a head.rav with it aswell, however it says to use face type 5, i am not able to do this, but if i had the 005.rav i could just rename that and install that into the head.big

PLEASE CAN SOMEBODY HELP ME!!!! I BELIEVE OTHER PEOPLE MUST GO THROUGH??!!!!! ;)
