Compression ratio

[Fbseis]

okay so just a quick question, but a bone stock k24z7 has a ratio of 11:0:1. My question(s) being is would you have to change the rods on any given change in compression ratio? Also, If keeping the same octane fuel, would going from 11:0:1 to 11:1 be able to combust more evenly on all cylinders without having to upgrade the valvetrain?
Looking into just a piston upgrade, but if needed a supporting mod to go with upgraded valvetrain as well.

K24z7= civic si engine is 11.0:1. It's 11.0 to 1. You're wondering if bumping to 11.1:1 is going to help?

Yea possibly, better combustion with faster crank if your able to shorten the bdc with the raise in compression.
