To clean up valve heads,pop valve in a drill, low revs, fine emery and CAREFULLY remove any carbon deposit. Don't go up the stem, usually there is a step onto the stem where it fits the guide.Stay off the guide part.
It helps to have the drill in a vice or workmate clamped solid. Better still a pillar drill or drill stand to take a pistol drill.
Don't wrap emery over the valve or you may trap fingers in it if it grabs, use emery flat.
GO STEADY
