    So, if you haven’t got the head off yet I’d suggest you do as George suggests and take the whole cylinder off with the head on it. With it off you can turn it over and use a 2 x 4 rounded up to fit the 2 3/8ths bore. Use the 2 x 4 as a punch to push the head off from the inside. A couple hits on one side then the other to try to bring the head off evenly. A couple of suggestions are not to try pulling on sparkplug threads. They will pull out. Take the sparkplugs off as the suction they make while installed makes it harder to remove the cylinder.
