2003 3.8 Engine Replacement

Hey all!
The 3.8 engine in my 2003 mustang tore up, and it's cheaper to put a low(er) mileage engine in it than to replace it. I've got a donor car (bad body damage, good drivetrain) and I'm going to swap the engine and transmission (automatic) at the same time. I was wondering: what I should replace while the engine is out of the car? The only thing that comes to mind is engine mounts.

...I can take it. I think.

Mounts is a good idea. I can't think of anything else other than pull the valve covers on the "new" engine and make sure nothing is amiss. I bought a 98 Cobra engine a few years ago in Louisville and brought it back home without at least pulling the covers. It had a burnt valve... something I may have detected just by taking off the valve cover.
