Choosing pistons

Hello, I need some help deciding piston type. I currently have a stroker kit for a 408 which includes; forged crank, forged h beam rods, and forged flat top pistons. I plan to run boost in this engine via single turbo. My question is; will I be ok with the forged flat tops? How much boost could I safely run with the flat tops? Or should I sell the flat tops and invest in forged dished piston? Thanks.
