Chris Would it not make a difference as you would expand the plug hole to the larger heat expanded size. The plug when it goes in although small is relatively cold and if manually expanded to the hole size quickly enough before it takes heat from the head it should be reasonable tight. It then will tighten further as itself further expands with heat. You are considering to similar metals expanding together. Not one hot and the other cold.
