Timed properly with the timing pin seating it can not be 180 out. The shafts from the cam gear are all connected off center. Remember cam to crank gear ratio is 2 to 1 - so no way to be off 180, if the timing pin was in the dimple the number 1 piston has to be at TDC - you don't have to look at the piston it CAN'T be anywhere else - unless the crank and camshaft gears were installed out of proper mesh.
