First time at the strip!

Have you figured out the max timing the engine can handle. IIRC, when in altitudes like you are, the engine can handle more total timing than something at sea level. The initial side seems in a good range.

A better carb could pick that combo up by 2-3 tenths and a few MPH. I'd put a double pumper on it, that's JMO. Drive it sensibly and it will get good mileage.

60' could be much better. Need to be able to mash it at the go. There's at least .3-.4 in time there alone.

I'd work on what you have and figure out to make the current combo go.
