Comp ratio???gsr crank-b20 block?

Im puttin a motor together. i have a b20z block and a gsr crank. going turbo with this build so i have also picked up a set of h beam scat rods. the problem im having is choosing pistons. if i go with a set of 9:1 comp pistons wouldnt that put me lower since im using a gsr crank in a b20 block due to losing stroke??

any input would help me...thanks

if you get GSR sized rods and pistons then compression ratio should be in spec for a gsr.
