It gets colder than crap here in the winter, I have stored many a motor in un-heated places.
I made these to seal off the exhaust ports, just use header gaskets and bolts.
They are made from 3/16 aluminum that I sheared to length and width at work, used a 3" cut off wheel to clearance the spark plugs.
I also leave the carb lift point on the motor, I use it with an old carb gasket, taped in the center to keep any moisture out.
