A little more detail would be interesting to hear - did the engine stop while you were driving? Did you try to re-start it? Does it turn over or is it locked up?

Obviously, if the engine is locked up solid then these comments are moot;

Have you considered fuel pump failure, MAF failure, electrical failure, or any other problems that would result in an engine shutdown? CEL on? What codes?

Its not that I don't believe your diagnosis, its just that I'd hate to have anyone tear into a good engine only to find that the problem was elsewhere and did not require such a costly action.

I'm sure that many of us would like to hear any more specifics that you'd be willing to share.

Thanks and sorry for your situation.
