Ancient Golem only increases bonus health - it has no effect on base health.

As for its interaction with runes, the %s will probably interact cyclically - just like Rabadon's and Vladimir's passive, or or Rabadon's and the Archmage mastery, etc. "+% increase health" will create more bonus health, which will be increased by Ancient Golem, which will then be increased by runes again, etc.

Or there could be an order to it, but Riot's never done it before - total health is increased and then the bonus health is increased.
