I'm pretty sure they are not used for anything.The threads are probably used in the factory for holding tool or summat.

They are the threads that the cambelt tensioning pulleys go into.

The front and rear heads are made from the same casting, and machined identically. When the factory builds up heads they make them into either front or back heads depending on the cams that they fit and which side the cams go in from.
