The cylinder head bolts need to be replaced as they are stretch bolts.
Once new bolts are fitted torque then to an initial spec of 22 Nm, 16 lb ft.
The second stage is an angle of 82 degrees using an angle attachment, see image below.
Please ensure that you tighten the head bolts in sequence, see image 2 below.
