Default LS1 Stock Fuel Pressure Regulator

Another quick question.
With my fuel system on my LS1 I'm running 80lbs/hr injectors in a billit fuel rail with a 400lph Walbro intank fuel pump.
Is it ok to continue using the factory fuel pressure regulator and returnless fuel rail setup ?

Or would you recommend running a return line back into the fuel tank and run a rising rate fuel pressure regulator mounted in the engine bay ?
