I've been advised by my A&P (that is, my Cessna 150 A&P, who has been involved in building two Lancairs) that concerns about engine break-in are real, and Lycoming's web site bears this out.  Bob Jude sounds like he has satisfactorily addressed the concerns.

My A&P suggests installing a run-out engine for the first 50 hours or so.  An engine that was removed because it hit TBO, but was otherwise functioning properly.  Work the bugs out of the airplane and then install the new engine. After the briefest possible ground run to verify no fuel and oil leaks, tow the airplane to the run-up area, start it up, take off, and run full-bore for an hour.  He recommends flushing the propeller with clean oil while the engine swap is being accomplished.

I'm not sure I'll do this, but I must admit, there's some attraction to this idea, mainly deferring the cost of the $25K engine for another six months...  - Rob Wolf
