Matt, run the biggest gap you can without missing.
The only really good way I can think of to do this is to increase the gap until your trap speeds start to drop, then come back .002 or so from there.
You need to be at an uncrowded track on test and tune day, with enough time between runs that heat soak doesn't throw the results off.
I had minor missing on the dyno w/NGK6097's @ .036, the car popped once or twice on each of the first 2 pulls, above 6k rpm's. On the final pull I had no misses at all. I figure .034 would be a safe gap, since the car is under more load on the street in 4th than on the dyno.
I was running 19 psi, and 100 Octane unleaded.
