Replacement parts before install

[clemsonteg]

So I picked up a 5.3 which supposedly had 140k on it, but after some digging I was able to decode partial vin stamped into the block and determined that it had closer to 190k on it. I pulled the valve covers and it looks clean, and I know that the truck was running and driving since it was pulled due to a collision. What parts should I look at replacing before I install the motor?

I was thinking of the water pump and oil pump. Should I upgrade the oil pump, even if I used a factory replacement? I already plan to replace gaskets to parts I am removing to paint the motor (intake, valve covers, exhaust manifolds). Anything else I should do before I put the motor in the truck?
