Eric---I question the wisdom of using wd40 in the cylinders. wd40 is a good penetrating oil, but it dries away to nothing in a reasonably short time. For a year long layup on a new motor, I would prefer using a 10-30 engine oil in the cylinders. I would put 5 or 6 squirts of oil down each plug hole. and then with plugs out I would use a set of jumper cables to the starter and let the engine roll over for about 20 seconds to distribute the oil throughout the cylinders well, then put the plugs in and store it.
