I'd do a compression test, to make sure you didn't warp a head, and blow a head gasket.

190 ain't so bad, but 250 is pretty scary. Water boils at 212, so you didn't have ANY water in your block. Just vapor...

If the impeller vanes came off then you will need to back flush to get them out as they more than likely went on into the cooling system.
