If it has a flat tappet cam you seriously risk wiping the cam out after storing it without having run the cam in first. This exact scenario happened to me with the engine in my Z11 Camaro. While it sits, the cam lube is going to drip off and no longer be effective when you need it. I would either get it started first and then store it, or remove the intake once you get it out of storage and relube the camshaft and litters prior to firing it up in the spring.

As for temperature, the thing that causes condensation is a rapid change in temp/humidity. If the garage is going to be 20 degrees the whole time and not change, that is ok. But if there is going to be a constant flow of traffic in and out with the temp rising and falling frequently, that's when the rust starts. If you have ever seen the front brakes on a car in cold storage, after the first rainy warm day when you open the garage door, you will see that they instantly surface rust right before your eyes.
