I assumed you'd be well aware that 12.7:1 is a very high compression for 93 octane fuel and that you would need to upgrade engine management, fuel and ignition systems.
Unless you've got the budget to run a couple gallons of C16 along with 93 octane unleaded in every tank, you'd be better served by reducing compression to about 11:1.
But if you're committed to making 12.7:1 run on the street, I would begin by consulting with your engine builder. Find out which ECU tuning program he prefers and get a sense of his (or her) experience in tuning hi-comp N/A motors.
You're not going to have much breathing room when it comes to detonation. And even though you're running forged pistons and con-rods, severe detonation will fracture piston rings and write off a block in moments.
