2002 BMW X5 3.0i coolant in engine oil, and engine oil in coolant

[beamer9]

Check Coolant led warning came up yesterday, overheated today, Coolant was dry. I dumped a couple bottled waters in to cool it down till I could get it to store to buy distilled water. I noticed the top of the Coolant cap had some oil mixed with antifreeze on the cap. Gallon of water didn't come out bottom but the engine took it all and it couldn't seem to get full. This evening I decided to add some oil, and the inside of the head was coated in orangish yellow oil mixed with water and antifreeze. I assume my head gasket blew. Any other possible culprits besides deformed, or cracked head or block?

Lastly, if it is the head I'm going to assume it's the gasket until I pull the head to replace and find out if its something else or I'm going to try some of the magic stuff that is supposed to repair a head gasket on the cheap.

Any advice?

Thanks,

Aaron
