VALVE SPRING COMPRESSOR ?

It depends on where the valve is broken. If there is still some of it in the port or in the combustion chamber, it should come out.
Support the chamber end of the valve on something solid such as a block of wood, head facing with valve springs up.
Get a suitable deep socket or something similar that is hollow & just a bit smaller than the outer perimeter of the spring retainer. Put the socket on top of the spring retainer & give it a couple of whacks with a hammer. The wood block will prevent the valve from moving down & the socket will drive the retainer down on the valve stem. The split keepers will fly off & release the valve. It may be that only on keeper will come loose on the first whack. A few more will get the second keeper loose. All you need is a wood block shaped to fit into the combustion chamber.
OR
With the same setup set the head in a drill press & use the drill chuck down feed to push the socket down. This works better if the socket like tool has cutouts in the sides so that you can grab the keepers & pull them out. You can even lock the down feed & have two hands available.
Using the drill press you can also compress the springs & install the keepers. In fact I've never owned a valve spring compressor.
An engine rebuilder showed me the hammer removal method 50 years ago. Been using it every since. Much quicker than a valve spring compressor.
