1999 PI Swap

Hello, I bought an unfinished project and i'm quite confused. Its a 1999 f250, but the motor that came with has PI heads that weren't manufactured yet to my understanding, and the holes on the intake that came with don't look exactly the same, but they aren't round or the skinny rectangles i've seen on the plastic manifolds. previous owner also claims it ran with those heads on it and the truck is not tuned.

It had to be swapped, or the whole engine is swapped.
