(except the head....don't do anything to the head when it's hot)
Like anim8r said, don't even remove the sparkplug until the engine is cold. If not, ya MIGHT damage the threads on the head.
The best tool bag I've used for years is that "green" grocery bag from the supermarket. It was free and it's held up very well.
