Couple thoughts

You didn't mention line honing or if the deck honing will be plate torque.

Assembly balanced?

Also, 8.33 is pump friendly enough. Dish pistons are said to actually cause increased risk of predetonation. Possibly more than the slight decrease in compression. I'm just above 8.6 dcr with a similar setup though AFR 63cc heads, flat tops, running premium with 34 degrees total timing and 10 degree vacuum advance. My 8.6 is a little more than I would consider perfect though, 8.3 sounds perfect. Though you wold be using premium gas.
