1999 Exp 5.4 triton PI Heads

Confused. I have a 99 expedition EB 5.4 triton.
From what I understand the exp did not have PI heads (PI=Square ports)
From the pictures I've seen, mine looks like PI.
The engine side stamp reads date 8-14-98 Windsor
Stamp also has 982260073, but google finds nothing on this #
The intake is aluminum- number xl3e 9425 dc
So I'm not sure if the motor was changed, special ordered, or the heads, intake were changed.
Even tho the stamp reads 98 would be made for the 99 with 99 specs?
