Raising CR in LZ9

hey guys, so I have this little 2.0L Honda. it is Honda's first production engine to get them over 100hp/L. the F20B engine has vtec and variable length intake runners and runs 11.1:1 compression ratio. I understand my lz9 has 9.8:1 cr. any experienced builders here with an opinion as to what kind of gains a bump in cr might be worth? on the 3.9L lz9 that produces 240x2 hp/tq

bump it to 10.5:1 and enjoy high octane fuel and the power delivery. You will absolutely notice.
