Hi Jonathan,
            If recutting the seats results in the head of the valve being 
below the surface of the head then you will be losing efficiency as the 
valve opening is effectively reduced, it's still better than having a 
poor seal though. Re-cutting the seat is certainly the simplest solution 
to pitted seats. 
If you do end up having to go for inserts you might as well go the whole 
way and get unleaded inserts and valves. It's expensive but then you'll 
have no worries for the future.

Cheers,

Keith Bennett                                Keith.Bennett@bbc.co.uk
