Harmonic balancer tightening (crank bolt) engine in car with 4spd manual transmission

I’ve built several and never seen any pins. I always tighten the timing cover bolts after the damper is on.

I would do the same thing. I just recall someone else pointed out the pins to me in the last few months.

I'm so confused!!!!

Found 2 photos... One that seems to show pin holes and one that does not?

I'm at a loss?????
