I took a large screw driver and grinded it down so I could get some leverage on it to push down the valve guide. The screw driver rests on the top of the valve port (intake or exhaust.
No matter what I did. I could not push the guide down to remove the guide keeper. So I went search for another tool.
I had a very large needle nose pliers which has a 90% bend at the end. The length of the bend was perfect (about 1/2 inch).
I opened the needle nose so that there was a tip on each side of the valve on the valve guide. Because there was equal pressure on both sides of the valve, it was balanced and when I lifted and it popped.
The pliers can be found at harbor freight for about $12. Not online.
