I would replace all the internal parts for sure. Items such as the cam sensor magnet and chain tensioner as well as the timing chain set. This is just my opinion, but I only use the original equipment Morse brand chain when doing this job. Optional would be a new crank oil seal in the front cover, water pump, crank sensor and coolant bypass hose on top of the front cover. All of these items are external and can be done without major disassembly after the fact, but if they must be removed and reinstalled anyway, or are exposed, I would consider new parts, especially if the history is unknown, or there are a bunch of miles on them.
