Be careful with this procedure though you can do it to hard and the keepers pop out and spring flies.
ORIGINAL: schwindty

No the lower can stay on, be sure the piston is at the top of its stroke or you will loose the valve.......thats a must! As well their are little keepers in the valves that have a tendency to fall out and down into the engine e sure to cover the area you are working on with a cloth or plug the holes in the heads with something......Another little tip is remove the rockers then get a socket the fits over the valve keepers, put it overtop and give it a wack with a hammer.... it breaks the keepers loose and makes it easier to fall out. I had to do this to all my valves to get the keepers out. Takes some time to figure a strategy out but once you have it it takes no time at all.

OK, here's my question. What is the engine doing and how do you know the valves are floating?
