Help with decking or not?

So im in the process of building a 340 bored 30 over and a 3.58 stroke. Purchased on summit.
Using scat rotating assembly
Stroke-3.58
Rod length 6.125
Piston compression height if im not mistaken -1.675
My deck height
LF-9.606 RF-9.600
LR-9.601 RR-9.610
I understand my deck height is not squared up, so my question is if i decked the block to square it up to 9.600 what would the set my Compression ratio at? My goal is to not exceed 10.5 to 1. Hoping i could get some input guys my block is at the machine shop.
