Did I just blow the motor?

So two weeks ago after coming home from a cruise night I noticed that my car was pouring out coolant. It was dark out but it looked like it was the waterpump. So today I put on a new water pump, AC delete, smog pump delete and a new fan clutch. I try to start the car up and it doesnt wanna run. I eventually got it started with my foot held on the gas pedal. I get out of the car cause it was barely running and was running disgusting. I could tell something was wrong. I look behind me and I notice out my tailpipes is about 2 litres of coolant in liquid form still. Under the motor was a huge puddle of coolant and some gas mixed in. The rad had emptied in less that 3 minutes and I pulled the plugs and they are soaked?!! What the hell happened? Cracked Block?
 
Check your top end gaskets. Then take off your heads and check valves and what not. Hopefully your gasket is just toast, if not....you might need to buy a new block.
