Best replacement pistons for stock '69 engine

Would the KB 167's put me over 9:1? I'd love to keep the CR low enough to not need 93.
Also, will they work with the floating wrist pin style of rods I have?

Cams are definitely another question for me (not to go down that road in an unrelated thread...)
This will be my daily-ish driver so a smooth (or at least not rough/choppy) idle and good vacuum are important
