It is possible, with care, if the design of the head is suitable, to use a hand drill on the stem of the valve, alternately in forward and reverse, at low speed, to make the job easier. If the seats are not too bad, and particularly if using new valves, you can often get away with going with the fine paste straight away. HTH :y

I've never used one, I've only ever used a sucker on a stick type, but this might be more suitable for you Webby  :y And as Chris says above, you'll find that it won't take too long to bed a new valve to its seat even with fine paste.
