The one other thing that isn't mentioned enough is running a center weighted crank. When I went to one in my Megablock, the cap walk issues went away. I spin it 7500 plus rpm, and the bob weight is heavy at 2432.
Do that in a 400 block, and I wonder just how much power could be put to the block and have it live a good life. Maybe as much as you could make with B1 heads?
