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.

With the 10.5 piston
.030 head gasket or OE .045 ?

Ported heads, zero deck, 1.9 intake 1.610 exhaust. SE 58 recommended?
