oil pressure

any body got any idea how to drop upper and cold start oil pressure , "with out" , dropping the hot idle pressure ????????????????????????????????????????????????????
Not loose bearing clearances, single line system, 7 qt alum. pan , full time restricted oil to the top end , hi volume pump.
AROUND 20 POUNDS AT HOT IDLE @1150 RPM : 95 ON COLD START UP.
Finally got under it and looked for my oil leak that I thot was my girdle to block seal, turned out to be the oil pressure looks like it over comes the filter gasket at hi rpm >???????
