Use the longer bore with that stroke ... an A460 block would be my choice.

Been looking at blocks too, was told the factory ones will be fine to the 800-850 mark

How hard are you turning it? Street engine?
I thought about possibly filling to bottom of water pump holes, I'm running methanol as well.

i would evaluate both blocks then select the one better suited overall (ie, cylinder wall thickness & uniformity, core shift, etc).

Paul I was checking out your site, going to do your mods to the block of I decide to use a factory block, what's the difference between your pump and the kasse pump and what kind of clearances do you like to see on the bottom end?

Give me a call at the shop and I'll be happy to discuss your current build and make some recommendations.
