Look at pg 251 of that file (15 meg). ACL 5ME pistons are dished. 5MGE pistons have 0.1mm extra compression height (no big deal - you have a mile of clearance) and are mildly high top to boot. This should put your static compression ratio well above 9:1. If you can then use a 7M crank and rods, the extra swept volume crammed into the slightly smaller combustion chamber should put you very close to the desired 10:1 you ought to be looking for.
