Oil pressure-How much is too much?

I finally got my 440 running. It's a street strip motor with about 11 to 1 comp. solid roller, 440 Source Stealth heads and a single plane intake. It seems to run well but I was only able to drive it very little because the transmission has an issue. My concern is the oil pressure. IDK what the bearing clearances are, I did not build the short block. It has a Sealed Power high volume pump. The pressure is about 80 psi at start up and has not gone below 75. I have not reved it over 4000 rpm. The oil is Valvoline 10w40 conventional. My questions are, 1) How much is too much? 2)Should I do something to reduce it? My biggest concern is having an oil filter burst at high speed. I'm planning on going to about 6500 rpm so I imagine the pressure will be very high at that rpm. I did install an MRL top end oiling kit and it looks like the rockers are getting plenty of oil.
