Engine Pi Swap

[arena314]

My 96 has a pi swap and I heard on a forum that someone bought a pi swapped 4.6 and it blew up 6 months later due to low oil pressure. I've had the car for 3 months and been riding it pretty hard and do regular oil changes my question is since my oil pressure gauge doesn't really work is there a way I could tell if it has low oil pressure by the way it runs? The guy that had it before me also bought the car after the heads were swapped and said he had it for over a year but didn't daily it. It's had the pi heads on it for some time now so do you think if it wasn't done right something would of happened by now? Lmk and thank you
