If you can make the facilities suit, I'd suggest the following menu:
Pull the head, with associated rocker gear retained in correct order, and inspect the bores. If it all checks OK, drop the oil pan.
Flip the motor and check the thrust bearing, and the rear main. Assuming both are fine, replace rear main oil seal as per the directions of Ford and using the Lexus sealant recommended by
wsa III. The 1/32" end offset is important.
Replace front oil seal in timing cover and be prepared to buy a sleeve for the balancer's seal running surface. Take care to seat the timing cover about the balancer, for maximum seal effect. With due care, reinstall oil pan to correct torque.
Turn the motor sunny side up, clean the head bolt threads with greased plug tap, and protect the motor top with rags or thick paper. Install the motor headless, as it will be smaller and lighter to do so. Reinstall the head (as discussed many time elsaewhere in the forum).

Fit your ancillaries, and go for it!
