I have been offered a set of heads and intake manifold to put on my 97 2V GT. I have been told they are from a 99 Roush. How can I verify that these are PI heads?
I can not find a PI marking on them. Do all PI heads have the marking? I was told they were from a 99 but I was almost certain all 99s had PIs on them. Correct? Also is anyone certain that if these are Roush heads that I would need new cylinder covers?

1999 = Windsor head, PI, square intake port. Non-Pi has a "tear-drop" shapped intake port. also if you use the Windsor heads on a Romeo block, you will need Windsor cam cvrs and some 10mm bolts and studs to attach the frt chain cover to the heads, as Windsors use 10mm and Romeos are 8mm.
