    Do a compression test of each cylinder.

    The valve clearance  will have no effect on plug oiling.    the only thing causing this is too much oil getting past the rings.   You may need to  use a non-detergent, non friction-modified oil until the rings bed in.

    What is the actual spark plug numbers you were using???
    Both for the NGK  and the Bosch??
    Plugs that are to cold will foul easily.
    There is a likely hood that a hotter range may help
