So I'm planning on building my 6 bolt. Shooting for 800-900hp. I have a magnus 100mm crank picked out and want to run 8.5:1. Just need some recommendations on what bore size, which pistons hold up to good power.
 
Imo it's best to always go to the minimum bore size, as you can rebuild that block more times. So I would only go .010 if it hasn't been bored. Pistons I think most would be ok, although I believe Weisco's non HD pistons have a reputation of cracking.
If I were doing a build that serious I would probably go with Magnus pistons, they know their way around high HP 4g63s, and besides, you already chose them for your crank, why not the pistons too? LOL. Make sure you have some good strong rods too.
