Or you can slightly enlarge the offset hole to let all 6 bolts fit.
That balancer looks like a Trick Flow?
Fred make sure to verify TDC with that balancer, just to be safe.
Looks awesome!
You will probably have to take off the damper bolt and washer before the pulley goes on. Also pending what year the crank pulley is, you may only get 5 bolts back in it. Early ones have an offset bolt. I ran one with 5 bolts forever. No issues.
