25-302BK Orifice size for DW300c?


I'm putting together a fuel system with a DW300C fuel pump in a return style setup with AN6 lines. (340lph) Currently the car is on the stock 270cc injectors and tuned to run on 93. The AEM FPR that I have comes with three orifice sizes. Since the fuel pump is quite a high flow, should I start with the medium or largest size orifice?
