Okay, I've got the new valve seals installed. I ran out of daylight so I haven't bolted the valve cover back in yet, so I haven't test-run the engine, but I'll just assume that I did it right

It's really easy to keep the valves from falling into the cylinder. With the cam's intake lobe in about the 11 o'clock position, you can actually press down on the valve spring and tap the valve on the piston! On two cylinders I even had to lower the piston a little to get enough clearance to remove the valve springs.
