Stories more involved for chiefs (9)

I believe the answer is:

sagamores

'chiefs' is the definition.
(I know this)

'stories more involved' is the wordplay.
'stories' becomes 'sagas' (saga is a kind of story).
'involved' indicates putting letters inside.
'sagas' placed around 'more' is 'SAGAMORES'.

'for' acts as a link.

I've seen this clue in the Sydney Morning Herald.
