On a serious note, If I'm storing an engine for some time here are a few things I do.
Remove the rocker covers and back off al the rockers. Having a valve spring compressed permanently for a long time will make it loose tension eventually. Backing all the rockers off means the springs will all be relaxed.
Remove the plugs and give the cylinders a good spray with CRC or WD40. Turn the motor over and spray a couple more times and replace the plugs. You want the cylinder bores to have a goad coating so they don't rust.
Drain the coolant
If there are no exhaust manifolds on there, sparay the exhaust ports with a bit of CRC and then tape them closed with some gaffer tape. Same goes for the intake ports if there is no manifold.
Tape or close up any openings to
oil galleries or intake manifold. You don't want any gunk or creepy crawlies getting in there.
Cheers
