I'd check the valve adjustment on those two low cylinders looking to see if they are too tight meaning the valves don't close fully during the compression stroke. If not that and it still doesn't start and you know you are getting fuel and its not the glow plugs, then it is most likely a blown head gasket.

Very possible with those numbers.
