The head is on the way and currently in Troutdale, OR. ETA is the 27th. Judging from the pictures the incoming EBay head might be preferable with only 3k miles although the old one was probably sealing perfectly. I'm inclined to install the replacement (as it was prepped by Kawasaki and not me) and fix/sell the old one. Below are pics of the incoming head.Has the replacement head been delivered? Hopefully it is as expected for you. Also, if upon removal of the head and you see the valves are seated as they should, would you correct what you saw from the top side and reinstall it?
