383 Oil Pressure Too High

My new built 383 oil pressure is high.
Idle pressure is 65psi @ 1000 rpm after warm up
5000 rpm is 95 psi.
Milage on the engine is 1100
The oil I’m running is VR1 20w 50
7 Quart oil pan, but I’m using 6.5 Quarts
oil filter is Fram HP4

I think the problem is the pump
I put in a Melodon 18756 , Standard Volume , High Pressure pump. I thought it was a standard pressure pump.

Do I have a problem?
Do I need to change to a standard pressure oil pump spring?
I seem to have a lot of small oil leaks.
