First happy Easter to all

Hello I am rebuilding a TR1 engine that was dismantled by the previous owner (not a good idea) the Haynes Manual shows 2 different head gaskets, one is round that also uses a rubber seal for the cam chain tunnel the other is one piece gasket. My engine has the groove in the cylinder for the circular gasket.

do I use only the circular gasket and the seal? This doesn't look right to me but thats what is shows in the manual. My TR1 has the tail fairing which I understand is the later model and should use the all in one gasket but the circular gasket came out.

Any ideas?

Ok thanks Nanno
