Celestial Markings

In going through the '61CH motor . . . I noticed these really weird lines in one cylinder.  I've never seen anything quite like this before.  They resemble rays-of-light.  The bore is straight, piston is slightly scored, but this is just weird.  It's a signal, a sign, a language that an engine builder needs to understand.  It probably has something to do with distortion.  I never babied this thing - so it's possible it got a bit hot a time or two . since gettin' your CH "hot" is fun you know . . . Like Competition Hot !
