I'd just oval out that one hole in the pulley with a Dremel or die grinder until a bolt can go through to the damper. I did that on the crank pulley I have probably 15 years ago and it's been on multiple small blocks since then revving past 5,000 RPM countless times. I suppose it's not "restoration correct" but once the engine is in the car with the radiator in front of it it's literally impossible to see the damper/pulley bolts. That Summit damper isn't exactly a restoration piece anyway... but probably better functionally.
