Default What’s going on here? LS3 Block


So I pulled the driver side head off this LS3 and see this. Is that from a bad ring? Or can tell me what’s going on here? Motor has 120k on it.

Some history/troubleshooting/symptoms?



But, all of this could be absolutely normal (to some extent)

The key is, what do your other cylinders look like??
