Most likely you seized the bottom end bearings, that sound your describing points in that direction. Soo yeah, spliity time.

If you seized your top end, it doesn't necessarily mean you broke the rings.

You will know once you pull the head and cylinder. If it's the bottom end, spinning the crank manually will feel chunky, gritty...etc..should be buttery smoothe. If it's the top end...well you won't overlook it.lol

Like I said I think I was running at 70. .there's probably an entry in the wiki with jetting info though.
