Motor Reseal - Input Requested

I've got a 1992 Bronco with the 351w and it's got a pretty good leak from the rear main and oil pan. Was just going to do the rear main seal and oil pan gasket for now, but the valve covers, front main seal, and timing cover are leaking a little so I'm just going to pull the engine and completely reseal it. Doing compression/leakdown first to make sure it's good at squeezy stuff. If it is, I'll also do the oil and water pumps while it's out. Timing chain was replaced recently. Probably won't pull caps unless there's evidence of an issue in the pan.

Anything else you guys think might be worth doing while I've got it apart? Roller rockers maybe? It's got 172k on it. The thought of a reman long block crossed my mind but I'd rather get some more miles out of this one while I start putting together a 460 or even a 7.3 Godzilla to swap in.

Appreciate any input you all might have. Picture for attention.

Also, does anyone know if the valve stem seals are positive or umbrella on the 92s?

I wouldn't bother with the oil pump. Sure, they're cheap... but probably just wasting your money & time.

Godzilla swap would easily outperform all but the most agressive 460 swaps.
