    You can replace the valve seals without pulling the heads,there is a tool for removing the valve springs,you'll have to pull the plugs and insert a rope into the cylinder(leave some hanging out the plug hole) and slowly use a breaker bar to bring the piston up against the valve(make sure you are on the compression stroke).I like to use a cotton rope,it is more forgiving on the valve,should someone get ofer zealous.
