SetFont Requirements?

Why does it take almost 2ms to change to font for a title? Is there a better way? Is it stupid to cache the original font?

Code:

     GUI.backgroundColor = Game.SetColor(39,39,39,0);
     var siz = GUI.skin.label.fontSize;
     GUI.skin.label.fontSize = 75;
     var fo = GUI.skin.font;
     GUI.skin.font = TitleFont;
     GUI.Label(Rect(0, 40, Screen.width, 75), Game.GetProjectName());
     GUI.skin.font = fo;
     GUI.skin.label.fontSize = siz;
     GUI.backgroundColor = Game.SetColor(39,39,39,0.75f);
