I have looked at mine and it looks almost like the area is not machined flat all the way to the top and I have looked at some on ebay and they look the same??!. Anyway sorry for the thread jack.
As far as I can tell the rocker blocks need to be tight against the head surface. I was unaware of any gaposis.
Something is not seating right...better pop it off and figger out what's holding it up.
