But unless you know a mechanic or Snap-on Tools (or Mac Tools, or Matco tools) dealer you are going to have an awful hard time finding one.

It is the one part # VT103
Real easy to use, real hard to get
Maybe, since you've torn it down this far, you wouldn't mind some old timey trick.
Warning this could get dangerous.
Ball a rag and put it under the head at one of the combustion chambers.
Take a socket approximately the size of the valve spring cap and another rag.
Place the rag over the valve you wish to dis-assemble.
Place the socket over the rag and make sure it is squarely on the valve spring cap.
Use a hammer to strike the socket.
!!!You are not trying to nail the valve to your workbench!!!
Use only enough force to push the spring down below the keepers.
Swift is better than hard. (its all in the wrist)
when done correctly the spring and cap and keepers will fly (yes fly) straight up and that is why you covered them with a rag. The rag keeps everything in one place so you can find the parts.
1 spring, 1 cap, 2 keepers.
The Metro valve spring is not very strong.
When you go to re-assemble, you can actually push the spring down by hand and have someone drop the keepers into the groove for you.
That is how I did mine at home last time.
Now I own the cool tool.
If you can make it to Virginia Beach before Monday we can tear it down on my bench.
If your helper doesn't mind dirt, you can push the spring down by hand and have them remove the keepers, but if you slip everything flies into a crack so you can not find it.

That black sheet metal with the crumbly rubber is a dust shield for the Timing belt. The crumbly rubber was great when new , just useless now. I cleaned mine off with a gasket scraper.
