How tight is correct for the timing chain?

The camshaft is an older mopar performance camshaft. I believe .484 lift 284deg duration. Is it possible that the two dots on the gear drives shouldn’t be close to each other. More like cam gear at 12 o’clock and crank gear at 12 o’clock? How do I know? I always thought that the cam gear should be at 6 o’clock and crank gear at 12 o’clock. Now I’m overthinking this.
