If your clearances are set properly, the std oil pump will be fine. You can swap the spring in the pump to the higher pressure one. The HV one can suck the sump dry during prolonged high rpms, but even running mine over 6500 for miles, I never had that problem. Also, if you choose to use a windage tray, use the Milodon one for the 4" crank. The MP one does nothing but cost $$.
