False Heads: How to change the shape?

I have a script(below) that makes a fake head within the character so that the nametag and healthbar are invisible. I am clueless on how I would change the shape of the fake head to the shape of the real one. For example, my character's head is Roundy, a spherical head. When I run the script it changes my head back to the default one. I don't know how I would change the fake head to be the shape of the real one(which is transparent at this point). I tried changing the mesh to spherical, not the right shape, tried exactly cloning the mesh, didn't work. I can't seem to figure it out.

game.Players.PlayerAdded:connect(function(player)
	player.CharacterAdded:connect(function(character)
	local fake = character.Head:Clone()
	local neck = character.Torso.Neck:Clone()
	character.Head.Transparency = 1
	fake.Parent = character
	fake.Name = "FakeHead"
	neck.Parent = character.Torso
	neck.Part0 = character.Torso
	neck.Part1 = fake
		if fake:FindFirstChild("face") then
			fake.face:Destroy()
		end
	script.ChangeColor:Clone().Parent = fake
	fake.ChangeColor.Disabled = false
	end)
end)
