Rocker, valve locks, retainers and springs have to come off. You will need a valve spring compressor.

I will be doing them soon. I am planning on replacing the seals without removing the heads.

or drop the piston, stuff some rope in there, and rotate the engine around to smash the rope in there and hold the valve up.

that way you dont have to worry about the air leaking out... just make sure you leave extra rope sticking out
