Timing gears and top dead center

[Smokedtires]

Hey gang, I want to run something by you all. With my cylinder head off, I brought piston #1 up to top dead center (TDC). I noticed the timing gears were not aligned as when I matched the cam gear to the crank gear timing mark. The crank timing mark looks positioned correctly to the gear keyway slot.

So my question is, should #1 piston be at TDC when the timing marks are aligned? Or is the piston at TDC when using the timing pin to locate the timing divet through the timing cover? I don't see how it is possible to change the relationship of the gear to TDC unless the crankgear is mounted backwards, I don't believe that is the situation though.
