It would be kind of rare for it to be frozen permanently. I highly doubt it unless a major event happened. Better double check that. Take out all plugs. Are these motors at the same place as you? If so, you will have to try to get bolts out. Probably will be almost impossible. Maybe thru various access holes and using ujoint sockets. But I don't think the motor is permanently frozen. There are methods of gradually letting pistons soak and etc. You don't say if the motor is in or out of a truck. You don't say why you think it's frozen. Lot's of unknowns on my end to be able to advise. Seems like info is being trickled out. Seems odd you would ask about getting at the bolts if you had the motor right there? It must be miles away.
