Stowing a motor Need Help

[The 92 Laser]

So I recently picked up a built motor for a sweet a$$ deal. Issue is Im deployed. Im home for 2 weeks of leave right now. I should be getting the motor in the next couple of days. I will be stowing it in a climate controled storage unit. The motor will be sitting for 6 monthes. The block and head are seperated.

Now for the questions.
Should i keep them seperated or put the head back on?
How should i cover it?
Put oil, lube or any kind of grease on it to keep the parts fresh?

Any input will be awesome.
Thanks Ross
