Firstly if you've got the engine apart to this level you should have the valves and seats refaced if they are reusable. I use bearing blue to check the valve face, put the head in a vice angled so the valve seat is horizontal, smear the blue on the valve face and then 'pop' it against the seat once, this transfers the blue to the seat, now clean the valve and 'pop' it against the seat again. If you look carefully at the valve face you will see blue transfered where you have a match with the seat. I agree with john you don't need to lap for hours and hours but a minute is usually enough
