318 LA Rotor position and TDC questions

Hi Guys,
I am getting ready to fire up my 318LA engine after a lot of careful work.

I am cutting and installing my plugs today. I set TDC on #1 cylinder when I installed my new timing chain aligning my timing marks to indicate that. Dropped in the new distributor, rotated my crank until the distributor rotor points at the intake bolt closest to the #1 cylinder.....Right so far? Now that things are all lined up, the timing mark is not even visible, which means that cylinder #1 is not at TDC right? If I keep going without knowing if there's a problem to correct, I might foul this whole thing up. Any thoughts? Thanks
