Replacing the Model of Player's Head

*If this is the wrong category, I apologize.
Hey, so I’m working on a game that has every category in ROBLOX. The player’s avatar seems to be looking like the avatar I like, but its about other people’s head model.

Now I’m not too sure if they have an “assetid” for the one I want, but I want the player’s head model to be the standard one as if you didn’t have a head equipped. If you don’t know what I’m saying, here’s a little picture to understand:

Is there anyway that I can change all player’s head model to be this one in the picture? I’ve been wanting to know this when I sort of finished my player model.

local plr = game.Players.LocalPlayer
local char = plr:CharacterAdded:Wait()

	char.Head.Mesh.MeshId = "rbxassetid://12345678"

This might work, but I need the head model like in the image I showed above.

The model is a mesh. just get the MeshId for the head and replace the rbxassetid. All roblox head shapes are usually meshes
