    Head Cylinder Cummins 6.7L?

    Hi, new member and new post: I'm building a 6.7L engine, and I'd like your opinions.

    I hope the translation is appropriate.

    Thank you.

    Welcome to the family, bud!

    Appears to be new valves but I see a bunch of metal-to-metal impacts from something.

    Is it appropriate for me to use it, or has anyone had the same experience?

    I would certainly figure out why that cylinder took a beating.

    Why was the rebuild needed?

    What's the back story on it?

    Yes, there is a seat valve problem.

    I installed the seat valve and valve but don't know if it will hold up.

    I recommend having a machine shop inspect the head for cracks and flatness, then resurface.
