This whole block of code shows where to go to adjust limb positions on the main body (my edits to head and arms shown).
Code:
   Head = Attachable
      CopyOf = Master Chief Head
      ParentOffset = Vector
         X = -1
         Y = -8//-9
   Jetpack = AEmitter
      CopyOf = Master Chief Jetpack
      ParentOffset = Vector
         X = -6
         Y = 2
   JumpTime = 4 // Secs
   FGArm = Arm
      CopyOf = Master Chief FG Arm
      ParentOffset = Vector
         X = -4
         Y = -5//-6
   BGArm = Arm
      CopyOf = Master Chief BG Arm
      ParentOffset = Vector
         X = 2
         Y = -6//-7
   FGLeg = Leg
      CopyOf = Master Chief Leg
      ParentOffset = Vector
         X = -1
         Y = 1
   BGLeg = Leg
      CopyOf = Master Chief Leg
      ParentOffset = Vector
         X = 2
         Y = 1
X and Y set the position. Higher number for X = to the left, higher number for Y = further down (flipped Y axis).
This is how you edit health, self-explanatory (edit shown).
Just in case you don't know, the // designates a comment, which the code ignores. Health uses the 125 and ignores the 100.
Attached file is edited code, along with picture of new placement.
FURTHERMORE, if someone comes with a question, don't just go LOL USE SEARCH NOOB. Tell them what they need to fix, and then tell them to use search next time.
The Mushroom Man, you did it wrong.
Classified, you did it right (though you could've said the variable was "Health" but I'm just nitpicking with that).
