He and I actually had a lengthy discussion about bore sizes and weighed the pros/cons. Given the goal, we decided to head this direction. I will also have lifter bore bushings put in, to help with lifter stability/lifter bore integrity at the lift numbers that we will be using.

What will CR be and are you setting up for 93 octane or 110 leaded
