This can be anything from improper lifter installation to a warped head, check compression in the cylinder, it's recommended to soak the lifters for several hours prior to installaltion in oil? Can be a bad valve, vale spring lifter, head or gasket.

Swap two of the fuel injectors to see if the miss moves. # Injector and what ever it most convenient. Orings were replaced correct?
