What I can see from the pict is that a ring caught in the exhaust port. I have seen more than once,maybe less than a dozen times over the years. All but one was caused by the ring breaking then popping out into the port. I would like to know if this was one of the newer high tension rings as I have feared this would happen with them. High tensile metals are not the best when subjected to heat, softer cast iron is better in my opinion. We will likely never know what the ring material was in this case but I will still be on the fence concerning the high tension rings.
That's what I thought too.....ring catch...hard to beat good quality cast rings.....I've run quite a few variation of rings over the yrs haven't found any better than Haystings cast iron.....I tried Total Seal rings in my Panhead once......the directions warned about using to much oil for prelube....as these rings are supposed to break in almost instantly.....near dry is best....I followed them.....but due to increased compression blew a head gasket at an oil return hole. ...almost immediately...Big smoke....changed that out .....but that cyl never had any oil control....ran great all summer but going downhill she'd lay down a "Gentle Blue Haze" as and old friend of my father's used say about our '48 Studebaker Commander out on the island...LOL!!!
