Sounds good. Start soaking the head nuts now too. Once the heads are off, I've found that a baseball bat dowel blank is perfect for beating on a stuck piston.

I know many guys save as much as they can, but sometimes you need to balance your time v. the cost. Meaning, red wrench saves a lot of time and effort in getting things out you'll replace more than likely.

Good luck and keep us updated on your progress.
