I see 2 plugs that are questionable. Did they come out of number 4 and 7 cylinders? Also noticed oil in a couple of runners in the intake shots. Is that something to consider or were those pics taken before final assembly? Reason I bring that up is that one of the runners with oil in it is number 7. Last question. Were the heads and/or deck milled and if so how much? You may need to mill the intake side of the heads so the intake manifold will sit down far enough to seal and not suck oil out of the lifter valley...
