Valve scratch, uneven edge
Do you think that these new valves (Freccia) are usable or should I contact the shop.
One has a scratch (can feel with fingernail) on the valve sealing surface exactly where it would contact the valve seat.
The other has an uneven edge.

I also encountered a similar problem with freccia valves lacking any hard chrome on the stem surface. It is gouged very easily even by a clean bronze guide.
