It may be well something that's fallen into the head while someone was servicing it and it hasn't affected anything.

I can't figure out what it could be however through process of elimiation...

Is it valve related? Unlikely.
Is it Cam related? Very unlikely.
Is it Valve cover related? Unlikely.
Is it HLA related? Unlikely.
Is it timing related? Very unlikely.

Personally I wouldn't be too concerned.

Do you intend on removing the head in the near future?

No I just plan on replacing the tensioner or the whole timing chain. Thanks for the response, eases my mind a bit haha
