My engine has been out of my 120 for more than a year now. I made this cradle to protect the engine during my moves. (Hopefully i will not have to move again!) anyway, the oil pan has been off this extended amount of time. Do you think the main seals have dried out? Should i replace them now since the engine is out? and if so, is there anything else i should address to the engine while i have it torn down this far? The car has 33,0000 miles on it and it runs fantastic - smooth and quite. Good Compression, so i see no need to remove the head.

I look forward to your response.

Dirt, grime, and grit is the major thing that you need to be concerned with. With the pan off, the lower end must have some of these things clinging to all of the surfaces that have been opened. Make sure that gets completely clean before putting the pan back on.

While the pan is off, I would use plastigauge to measure bearing clearances. I my own opinion, I would replace the seals. But you could remove the crankshaft end caps and examine how pliable the seals are.

Also, this would be a good time to replace the freeze plugs with brass ones.
