Dear NC:

Go to NAPA and see if you can buy a valve spring compressor for a flat head motor.

Then take those valves out. The minimum you need to do is polish those valve stems so that they don't collect gum. Also buy a wire brush to clean out the guides.

If the faces are clean then grinding them may only serve to reduce the margin. I knew old timers who swore by this method and I guarantee that if all you do if free them they will stick open again.
