as others have said, replace what you can. So this used engine with lower miles at 100,000 is it the same type and year?
I would change the rear main seal and the trans. front input seal.
as your doing the timing chain new plugs too. also, the engine mounts, and drive belts. the list is getting bigger.
How is the old one shot? And do you have the Ly7 or LLT engine? If you have to swap out the engine anyhow you might consider upgrading to a newer LFX or if you have the cahones a v8. There is information out there on upgrading to a newer motor. Or you can even try rebuilding your engine as long as there is no major damage to the block and heads. By rebuilding if you have an LY7 you could turn it into an LLT. Or other such upgrades. Otherwise if you are swapping motors I would just change some of the gaskets such as the ones mentioned that are hard to get to, maybe the thermostat and call it good. New fluids of course.. And would change the oil again after 500 miles.
