With the 5.3 out, what parts are you replacing?

Was thinking a full gasket reseal, new oil pump (maybe a high volume one but not sure of the pay off on it) knock sensors and harness, head bolts, lifters, cam (as needed) oil pickup tube and screen with new gasket, engine mounts and lower trans mount.

Was going to just do gm parts unless there is an aftermarket that is better you guys have used. Feel like I might be forgetting stuff but want to make this thing bulletproof as it will be a used pulled motor from eBay from a reputable seller.(aanda_autoandtruck)
