Casting number: X6889668

Those looks to be the numbers to me. Unless it is possible that those aren't 6's and they are 8's.

Any info on these heads would be much appreciated. Thanks! :beers:

Can you give us a little help, like what engine are these on or what were they on and what is the casting date?

I did just a quick check and I could not find anything based on what you posted.
