Head Work - Valve Lapping

So with the head all ported, and polished i moved onto seating the valves.
This is called Valve Lapping, 

"Valve Lapping is basically sanding down the surface of the Valves (which allow fuel and air to flow in, and exhaust to flow out) and the Head (Holds the Camshafts and valves) where they make contact with each other. This is done by applying a Compound Paste (pretty much just oil and a fine grade of sand) to the edges of the valves and spinning them in their seats on the head."
