Bolt tightening depends if you have a "Suffix B" engine number or not.

Engines without Suffix B use torque values only. Engines that do have Suffix B use torque values plus two 90deg rotation stages. The bolts for Suffix B engines are stretch bolts, hence the sequence !!

Note: the workshop manual specifically says Suffix B uses "NEW" bolts. That is because they are stretch bolts.

It s a non suffix B so it 's the "classic" torque sequence with standard bolt.

I bought a Elring Fibre Composite gasket 916.059...can't found the tickness but it's not a tin one.

arrived today , very good quality indeed ! it's not a composite but called "soft metal"...may be the same.
It's 1,4 mm (less one time compressed) and 0,15 mm more near the outerside of water hole (red line) , that s a great evolution because of the often leaks on this part, almost for my heads that are less tick on the ends.
I'm now more confident to put back my heads...
