 Jim, I would be asking for a "new" engine, not fixing the old one.  Why
wouldn't TCM be responsible? Others on this site will have a better idea on
your chances of success than me.  However, I can assure you General Motors
would replace the engine if you made a big stink.  Secondly, the person who
OK'ed the ferry flight with visible hunks of lifter in the oil filter was 3
french fries short of a happy meal. Spald lifters do not heal themselves and
nothing positive could come from flying that engine.  I'm very happy it all
ended successfully.  I am 100% percent certain that all bearings at a very
minimum will need to be replaced.  I would make a big stink for a new engine.
 If they insist on a rebuild, don't forget about such thinks as oil cooler,
etc,etc....anything that sees oil.
