I wanted to share this with you DIY guys out there.
I bought this valve spring tool at a local tool discount store. It is too large for removing my VR valve keepers and I had to use the old stand-by . . . a deep socket and rubber hammer. However, it worked great for installing the valve springs.
To hold the valve closed I placed a rubber sanding block under the head and in the dome. I then stacked the valve springs and top plate, set the keepers in position, and pressed the tool down on the top of the valve stem. The tool has a spring loaded pin that helps guide the keepers into position. It took a little muscle to press down, but, it worked!
