Can you put PI Heads on a Windsor Engine?

Yes, you can put PI heads on either a 4.6 or 5.4 windsor motor. From mid 1999 and up they started putting in the PI heads. My 2000 5.4 windsor (manufactured in december of 1999) came with PI heads.
As for installing them, i'm pretty sure they bolt right up. Even the valve covers should be the same (not 100% sure though), but i think the only difference in the heads is the intake ports and intake manifold. So you're going to need a new intake manifold for the PI heads.

This trivia took hours and JBrew to locate, so I wanted to save it where it might be found.
The aluminum manifold was made for the 5.4 only 1999. In addition, mid 1999 was said. My Windsor was dated 5-1999. I was sweating it. The paper label was still on mine, on the driver's side of the block. ~"Ohh, CAAaaNaDa, Oh Canada..." (Just a lil fun. Feeling V happy after inspection my donor engine.)
LOOK on the passenger side head's outboard side, near the front, for "PI," under a few other numbers. Not all 5.4's apparently have this mark, but if you see it, you are golden, in that regard.
