Anyone using SB Lunati cam ending in 703 Part number?

I us
Did you verify that the damper mark is truly at TDC? If you timed the cam without the damper on, then the accuracy of the damper mark is not known.
I thought about this. And this could be my issue. I set the motor up with timing marks on the drivers side and it is now set up with mark on the passenger side. I do currently have a 68-9 balancer on the motor with TDC mark for passenger side cover. Any ideas on how to confirm at this point?
