About 98k on the truck and 96k on the motor. It runs great and has plenty of power but just has high pressure.

As has been noted the high pressure doesn't make sense. Can you verify the gage reading? as in changed the gage, or sending unit. You may be able to borrow/loan a tool from the local parts store that screws in where the sending unit goes to verify oil pressure
And can you run a compression test?

I’ll see what I can do this week on a compression test and oil gauge.

You could get something like this...

you don't have to permanently mount it, but it would answer questions for not much money
