I've currently got my truck blown apart to replace the injectors and I just keep collecting more stuff to put on it at the same time.

I pulled the driver's side manifold off to put an LML manifold on, searched around about re-using the head to manifold and manifold to up-pipe gaskets, some say re-use them and some say replace them. The truck has 225k+ miles on it and all original, so I decided to get some new gaskets. Got some Fel-Pro gaskets and they look like total crap compared to the factory gaskets.

Should I use them? Or re-use the factory ones? Or just go to the dealer and get new factory ones? I've never had issues with Fel-Pro, but their manufacturing process on these particular ones is crap.

Ask yourself if you want to risk replacing them again if the Fel-Pro ones leak. If you think they won't leak, use what you have; otherwise get OEM. I am a fan of the OEM parts, myself.
