I usually use mediun valve grinding compound. If you have never lapped valves in before I dont recommend using a drill, you can groove the valve and seat easily doing it with a drill and then you will have problems. Just get the suction cup valve lapping tool at you local auto parts store and the compound there too, Ohh, be careful to not get any in the guides when doing this as that can cause big headaches too.
heres a link that may shed light on the basics of head work, hope it helps you out.
