Cylinder wall problems ( never seen anything like it)

Do you guys think to much rpm could do this. The last run at the stip was the worst, the engine was very hard to start before I was going to warm the tires ( has never been hard to start before ) I started in 2 gear and reved it to 7000rpm as usual and after the burnout the engine started to run like a bag of nuts, shut down on cylinders and so on.

But when I lined up against the tree it started to go on all 8 again so I thought what the h# and ripped of a bad 12.88 @ 103.1 but a decent 7.98@1/8
After that I got home and made a Leakdown and compression test And the readings were all over the place so I took it apart and found the discoulor and dents.
