Ok, I have a cracked 0331 head. I know it's common. Already have a new head on the way. I plan on running without changing the bearings for now. Only ran it for a week with the crack. I need a good way to drain all that milkshake out of the engine. Any thoughts or suggestions helpful. Thanks

 

Multiple frequent oil changes and multiple frequent flushes of the cooling system.

For the cooling system, I'd use a moderate cooling system additive designed for cooling systems, available at any parts store.
