How do I sync head rotation over network?

So I got this code to make my head rotate vertically with my mouse, I tried syncing this over the network but can't seem to get this to work. I've seen alot of threads on this and Unity's forum but still haven't got a good solution, this guy figured it out 'https://forum.photonengine.com/discussion/18057/moving-a-bone-on-a-humanoid-character-best-way-to-do-this-in-pun', But I don't really understand it.

Here is the code I use which works locally:

using System.Collections;  
using System.Collections.Generic;  
using UnityEngine;  
using Photon.Pun;  
using Photon.Realtime;

public class HeadTilt : MonoBehaviourPunCallbacks, IPunObservable  
{

    public Camera cameraRot;  
    PhotonView view;

    private Vector3 objRot;  
    public Transform head;

    // Use this for initialization  
    void Start()  
    {  
        view = GetComponent<PhotonView>();  
    }

    void LateUpdate()  
    {  
        if (view.IsMine)  
        {  
            Vector3 tmp = cameraRot.transform.localEulerAngles;  
            tmp = cameraRot.transform.localEulerAngles;  
            tmp.x -= cameraRot.transform.localEulerAngles.z;  
            tmp.y = 0f;  
            tmp.z = 0f;  
            objRot = tmp;

            head.transform.localEulerAngles = objRot;  
        }  
    }

    public void OnPhotonSerializeView(PhotonStream stream, PhotonMessageInfo info)  
    {  
        if (stream.IsWriting)  
        {  
            stream.SendNext(objRot);  
        }  
        else  
        {  
            this.objRot = (Vector3)stream.ReceiveNext();  
        }  
    }

}

The LateUpdate checks IsMine. So the code in that block will only run on the controlling player's client.
Is that intended?

Yes, I want every individual player to have their head rotate up and down with mouse input

There is no code that applies the rotation for non-local players. OnPhotonSerializeView reads the incoming value into a local variable and that's it.

Found a solution. for everyone trying the same thing, put this script on your character:

    private Quaternion server_head;  
    [SerializeField] private Transform Head;  
    private void LateUpdate()  
    {  
        if (photonView.IsMine == false)  
        {  
            Head.localRotation = server_head;  
        }  
    }  
    private void FixedUpdate()  
    {  
        if (photonView.IsMine == true)  
        {  
            photonView.RPC("RPC_UpdateBoneRotations", RpcTarget.AllBuffered, Head.localRotation);  
        }  
    }  
    [PunRPC]  
    private void RPC_UpdateBoneRotations(Quaternion h)  
    {  
        server_head = h;  
    }

RPCs are very ineffective to do this. You waste quite a bit of network traffic and messages/sec this way.
Better use OnPhotonSerializeView.
