Since you'll have a bunch of stuff tore apart down there:
Front main seal
Oil pump gasket
Thermostat body o-rings and sleeve
Transmission cooler lines
PS pump hoses and cooler
Too late to the party, but for future reference (adding to all above) also a good time to check the water pump and alternator while the belts are off ie: for roughness/noise (bearings). Also the alternator belt idler pulley, replace alternator brushes (or new alternator), modify or replace the fan clutch if needed, ---
It can become a long list of "while you're in there" services.
To add to the already mentioned stuff.
If you're in there with all that stuff removed.
Blue Fan Clutch
power steering pump diy rebuild or reman
New low pressure line PS hoses
New high pressure line PS hoses
Maybe a refresh of the PS Box itself.
All this stuff up above is leaky and part of the cause of the oil everywhere
By then your on the driver side block.
Maybe knock sensors
It can keep going and get out of hand. But you'll have all the PM stuff done
