Im getting my block Cold Tanked in a couple days(I put Hot in the title for future Searchers) what all do I need to remove?

 

All the plugs,all the sensors.

Thanks Glenn,
If anyone has them I need the size of socket needed for the Knock Sensor, Oil Filter Deal, and the Allen Wrench size for the Freeze plugs,

Also just for clarification what actually happens when the block is cleaned?

 

Not sure what they are referring to as a cold tank.Most shops now a days have spray cabinets.Think of them as a dish washer for engine parts.The parts sit on a turn table and a hot detergent is sprayed on them from nozzles all over the inside of the cabinet.The older hot tanks just soaked the parts in hot detergent.
