    Oil pan question. Timing cover not flush

    Wait a second is it a stock oilpan or a moroso canton aftermarket type? If its aftermarket they say that it may not fit flush because of the welding on the pan you have to follow the torque sequence to pull it flush My moroso 351W swap pan was the same way even if it is stock it may have warped...
