Hi all!

After being almost done with polishing (ports, combustion chamber) the 160 head off my 1979 B21F, I discovered an extremely fine crack between the valves in combustion-chamber #3. There is no sign whatsoever of that crack having leaked yet nor does it show up in the intake or exhaust bowls. May I leave it alone and just install the head back on or is that crack a catastrophe waiting to happen?

Many zillion thanks in advance and a good day to everyone!
