If you have oil pressure, why would you be afraid the top end isn’t getting lubrication. Hydraulic lifters, right? If you had no oil... you’d know.
Remember... it’s just a car.
Oil pressure will be high if the galleries are plugged/restricted. If the car has an oil pressure gauge installed, check to see if there is high backpressure. If it has no pressure gauge, it is a minor issue to pull the covers.
