alot!

you will need a set of domed Z6 pistons... i say just use the oem ZC pistons...

your CR with a set of stock z6 pistons will be like 7.7:1

to get compression ratio of 9.0:1 with the DOHC ZC, using SOHC pistons, and without milling the head, you will need pistons with compression height of 1.181" (30mm) and a dish of not more than -0.5 cc - something like Arias #3330900
