1995 Ford Taurus cracked head, cracked block, or head gaske

I have a 95 taurus and the weather was severely cold -30 degrees the car started fine and when I drove off I noticed I still had no heat I assumed that it was really cold and just kept going fifteen miles later the engine died it sounded like it wasnt getting compression when I tried to start it I tried to thaw the car when I got it home but it never started again so I started to tare it down hoping to find the problem I found antifreese in the cilinder do I have a craked block?? the oil isnt discolered but is runny and smells like gas
