Bummer guy. Warped head, or bad block decking, or bad headgasket install, or any combo. Do you need to add a little warter/coolant every other day or so? I do, because water is getting into the combustion chamber and burning off. My heater don't blow hot half the time either. That's my sputtering anyways. Good luck.
