Ok so my original built head is garbage, cracked. Supertech valves in it just got seated as the car had about 1k km when I noticed the crack. Valves have about 1k and have a noticeable line on the valve face where it was seated to the old head. Old head was fully rebuilt and valve seats were cut to 3 angles so obviously seats aren't exactly the same width etc as new head.
I threw in those valves into new head and they are holding alcohol with no leaks. Do I reuse these valves or should gett a new set? I think it's pointless to lap valves here because the face of them is perfect and the contact line ( I assume it's the edge of the valve seat contact) will not be at the same spot once valve under the spring pressure.
