Too far gone.
If there's scale and pitting from rust, that's way beyond the capabilities of lapping compound. The valve seats will need to see a doctor, quick smart. Remachining will alter the depth of the valve pocket, so save up too for a set of adjustable lifters, as getting your machinist to do it the original way by grinding valve stems will cost you just as much in labour (and cost you too much goodwill with the machinist
 )
