LQ4 service items before install

[C.I.Blazer]

Getting ready to prep and paint my motor in anticipation of setting it in for the first time. The motor has 130k miles on it and ran well prior to removal (at least to the best of my knowledge). Everything looks pretty clean to my untrained eye. I want to try and get everything running in stock condition before I start thinking about upgrades.

Are there any service items that I should do while the motor is out and easy to get to? So far I am planning on knock sensors and wiring harness as well as replacing the valley cover gasket since I will remove it to use a lift plate. Of course I will also do plugs and wires. Any other common failure points? Oil pan gasket looks good with no leaks. I have heard about some issues with the oil pressure sensor?

Thanks for the suggestions.
