If crank does not rotate via hand tools, then the head-gasket has/had a leak, and one cylinder/piston is rusted.

Remove head...

I don't think the head gasket is blown, what happened is this, someone put some water in the tank, at first I thought it was out of gas, while figuring out
how to drain the tank without taking it out of the car, the engine got stuck and would not turn with a breaker bar, so I removed all the spark plugs and sprayed penetrating oil into the cylinders,but it's still stuck. next step is to remove the head

The storage and stability of ethanol blends are special issues due to ethanol’s affinity for water and the risk of phase separation. In addition, ethanol tends to clean impurities from fuel tanks and lines leading to risk of plugging the fuel filter.

The effect of water differs significantly depending on whether the water is dissolved in gasoline or is in a separate phase. A small amount of water in a homogeneous fuel has no adverse effect. If phase separation occurs, the ethanol/water mixture stays as a layer at the bottom of the tank and the octane number of the gasoline layer falls. The engine stalls if it takes in the ethanol/water phase. Furthermore, a mixture of ethanol and water is corrosive
