Engine Down

[Hammerhead]

Speaking on the subject of new head v reman, what protocols for long term storage of such a part be taken?
I have my own theories and am looking for others thoughts as well.
I ask because while I was having issues in Vegas and was thinking I had a cracked head in that case, I inquired about a new one from KW. Since Edm KW at home told me new wasn't available I checked while I was in Vegas. They had one at the warehouse and brought it in for me. It's at my shop now, and I didn't have a head issue, so it's become inventory for the inevitable.
I am planning to:
-decompress the valve springs by removing the collets so the springs don't become fatigued
-I have an oil tub that is the perfect size, so I'm going to submerge the head in oil and seal tape plastic over the tub to prevent oxidation

Anything else?
What would you do to store it for a probable 4-5yr term, truckin gods willing?
