4th Gen TL (J347A4) OEM Swap related Question

Hey all, made a previous post asking what to do with my '14 TL since it threw a few weeks ago.
Since then I've sourced a junkyard motor that I think I feel good about and might grab later today. The motor currently has around 72,xxx miles

From what I remember, 4G TL's usually require valve adjustment, timing belt / water pump at 75,000

My question is this: should I try to get the valve adjustment, timing belt / water pump done now while the engine is out of the car, as opposed to putting it off until potentially 75k or later?
The logic here is that doing it while it's out of the car should cost fairly less?

Any guidance would be appreciated thanks

Yes.

Do those services while the engine is still out of the car.

IIRC the timing belt/water pump is 105k miles, and the engine should not need a valve adjustment at 72k. You can check the spec but I doubt it would need any tinkering with.

remove plugs and throw some BG 44K into the combustion chamber to help remove some carbon from the rings. Use compressed air/vac to get it out and change oil.

Look over the whole motor and see if there are any leaks/weeps! Better to resolve it now then when it's back in the car.

Timing Belt water pump is usually 105K so you have some time.
