dyno session

I`d turn the oil pressure down to 70 psi ,more hp. I run 70 at 7200rpm

And what type of rocker is being used, how much valve spring load there is and probably a couple of things I’m forgetting.

At 8500 I was at 105 psi and it made more power than at 90 psi.

The bushed rockers and 800 plus over the nose didn’t like the lower oil pressure.

Oh yeah, the cam bearings looked better with the pressure up there too.

If you have needle bearing rockers you can run a bit less pressure. Maybe.
