I recently used a set of eddies dated Nov 2014. Tried to pull the valves out and they were all jammed in the guides. Sent them to my machinist who honed the guides, machined the warped decks and did a valve job as several valve seats werent concentric. However i was expecting this as its pretty normal for out of the box heads to be all over the place.
Could have run them as they were but didnt want guides that are flogged out in 20k miles and lost power from leaking valves
