Now it becomes a deeper dive to determine the exact compression based on fluid measurements.
A 107" with flat tops is at 10.4:1 with flat tops, 0 deck, 85cc heads and a .030hg.
The CR575 will be right at home there assuming a good tune.

Can the CR 575 run with 10.5 Pistons?
Yes, 10.5:1 compression isn't a problem.
