I replaced valve seals on my old V8 Dodge years ago by taking out the spark plugs and then inserting a few feet of clean clothes line rope into the cylinder to fill up the combustion chamber so that the valve wouldn't fall into the head. I brought the piston up most of the way to TDC then pushed in a long length of new rope. When it seemed mostly full I would then turn the crank a little more by hand to tighten the mass of rope up against the valves and hold them in place. Then use a spring compression tool to remove the spring. When done then back the piston off again and just pull the rope out.
