I bought this 6.0L LQ4 engine recently that is supposedly from a 2005 Yukon Denali XL. Are these factory OEM pistons? I have searched the numbers listed on top and I don't get any results. Also, I haven't seen any other OEM LQ4 pistons that like identical to mine. I was hoping it was an unopened engine.

Yes, they're stock.

Is it just my phone or are 2 pistons in that picture burned.

Good, thank you for verifying. For some reason the cylinders were filled with oil on top of the piston when I removed the head, at least the front two driver sides were.
