    You have got the area circled that I am referring to…. Probably just some schmutz that the head was laying on after removal. The only reason I pointed this out was to emphasize the importance of inspecting the block/head mating surfaces carefully. This series of engines is known for aluminum erosion in this area….
    OK, so the gearcase is seized also….You better pull that apart to see if it is salvageable before going too much further….
