You have to remove the keepers. They are what "keep" the valve spring compressed. You put a little grinding compound on ...enough to thinly coat the surface of the valve, and then you use a twisting motion like you see starting a fire with a stick with a tool about 15 bucks or you can use a kids suction cup dart from his dart gun. What you want to accomplish is to get the two surfaces mated. They need to both seat without pitting or restriction. Just like your head surface. They will then have a positive seal and once again last for many hours without being an issue. That is not to say though that they will never need their adjustment checked/adjusted.
This might sound like a lot but it isn't. Actually pulling the head is the most work. And you have that done. Take your time, don't rush and when you are finished you will not only be rightfuly proud, you will have a great running engine. ... I promise.
