    If you're just installing new valves thats it. Lap them in and go.

    head off, springs and keepers out. lapping compound and a wood stick with a suction cup on the end. spin spin spin. You;re just lapping the seat surfaces. Don't be a yahoo and put a drill on the stem and reef on it.

    Make sure you get ALL the compound washed off when you are done. It does REALLY bad things to valve stems and guides(Don't ask).

    You got good replies. Just an additional comment- you can use a drill on the suction cup, saves your hands a bit. Don't grind by pushing and spinning fast, just lap slow and gentle like. :D
