Here's a tip. We've all been warned about junk in the supply galleries in the cylinder casting clogging and killing the valvetrain. Before reassembly to make sure they are completely clean, run a .22 rifle bore brush through the gallery. If a brass brush are not available, go to your local hardware store and look for a percolator brush. They use nylon bristles, but still do the job. Don't use a rifle cleaning "barrel mop" as the drilling operation to form the gallery usually leaves the gallery walls rough and will grab lint, which could work loose and cause problems later.
