Held block rotation

So I have a block with a meta-dependent texture, but when it's held it shows the wrong faces

http://prntscr.com/a8qlxy

How can I rotate it to show the face of the machine?

here's my rendering method:

@SideOnly(Side.CLIENT)
@Override
public void registerBlockIcons(IIconRegister reg)
{
	this.icons[0] = reg.registerIcon("sporksstuff:generator_bottom"); //bottom
	this.icons[1] = reg.registerIcon("sporksstuff:generator_top"); //top
	this.icons[2] = reg.registerIcon("sporksstuff:generator_front"); //north
	this.icons[3] = reg.registerIcon("sporksstuff:generator_side"); //it literally says in the name. Why am I writing this?
	this.icons[4] = reg.registerIcon("sporksstuff:generator_front_active");
}
  
  @Override
  public IIcon getIcon(int side, int meta)
  {
	  if(side == meta) {return icons[2]; }
	  if(side == meta-6) return icons[4];
	  if(side == 0 || side == 1) return icons[side]; //top & bottom
	  return icons[3];
 }

Thanks
