Please help!!!! 454 TBI OIL PRESSURE MAXED
So, I have a 1992 chevrolet 2wd c3500 with a 454 tbi. I changed the oil in it and 2 days later my oil pressure shot up to 60psi and I blew the passenger valve cover gasket. I replaced the gasket thinking nothing of it and blew the new one on the way home. It stays there at idle and goes past that when I put it in gear.
I replaced the pcv valve and ran new vacuum lines. It has a crazy amount of vacuum. The oil drain holes in the head is clean.
So....I'm stuck. I have no clue what I do next. This is my work truck and the way I make all my money. PLEASE HELP.

must be a blockage somewhere. try measuring the pressure before and after the oil cooler.
