Could stretch the springs slightly as too much pressure will obviously make all the seals leak. Best bet would be fit it up if it feels underpressured get it flow tested and pressure tested as these are the 2 valves in your powersteer pump.
plenty of parts on the bench

going to a larger pulley will cause the pump to turn slower. you need a smaller pulley to increase pump speed.

as high as you can rev the engine? On my 4Y that get's to over 6.5K rpm.. not that I would even dream of holding it that high for any longer than a microsecond.
