How well drained was it before the heads came off?

Sounds like something I wouldn't even bother sending to the shop.

Re: Water inside pistons

Could the heads have been untighten and then drained in?

Re: Water inside pistons

With a bent rod and water in the cylinders it's a pretty safe bet there's a crack somewhere. It doesn't mean the block isn't salvageable, but the cost of any repair will certainly cost more than another core.
