Nasty looking piston! My valves are one piece. The rockers you show are the same. The price on Amazon is for a set of 8. And price per part is 23.96
Mine is for 12 and are 23.33.
The bust ring lands are from the turbo abuse and not controlling detonation. As Hank said, even a forged piston can fail from detonation. You will want to address this with your next engine build.
