If your plan is to rebuild it, I would not worry about it too much as long as it is well sealed.

Change the oil, mostly to remove any moisture that might be in it. Squirt oil in the cylinders, and then leave it in a corner.

If you wanted to use it as is after years it would be a bigger problem because you need seals and gaskets to remain useful, but that doesn't matter in this case.

If you follow some of the posts here you'll find guys who have started and run motors that were just abandoned decades ago. Keep the moisture out and you should be fine.
