831.221 is the Elring part no. for the later 130 engine head gasket. They are OE gasket suppliers. MB equivalent is 130 016 5620.

You will have to see if you need standard or oversize valve guides.
108 050 0624 Std exh valve guide
123 050 0167 Valve stem seal - engine set
The cylinder head and gasket are different from earlier 130 engines but the same valve guides and stem seals seem to be used. Hopefully, somebody here can confirm this.  :?:
