Any ideas on how to change the default human to look different

Sorry to bump this post but I am wondering if someone can help me customize the Terran male. I can not seem to find the reference for him, this is what I did so far and I got the torso right but the head is not taking as I do not know what they named the Terran male start character model.

<diff>
<replace sel="//macro[@name='character_player_terran_gamestart1_macro']/properties/models/model[@type='torso']">
<model type="torso" ref="assets/characters/argon/bodies/ch_ar_m_body_d-pilot_04" />
</replace>

<replace sel="//macro[@name='character_pioneer_male_plot_pioneer_gamestart_actor_macro']/properties/models/model[@type='head']">
<model type="head" ref="assets/characters/argon/heads/char_arg_m_head_cau_03" />
</replace>

Is this done using the save game file? I can't find the file that we are supposed to edit where is it stored?
