B20 Overheating! 140-160

I think there is a good possibility you've blown a head gasket... which may have been the source of the overheating problem in the first place.

This will usually show up as bubbles in the radiator (or expansion bottle if so equipped). Fill the cooling system, start it and let it warm up, then check for bubbles in the water. There may also be a gassy (exhaust-like) smell at the radiator cap opening or at the open expansion bottle with the engine running.
