Pi Heads?

[Phatt_daddy]

I recently came across a deal on a complete PI swap ( 150 for the complete top end) Anyway when I went to meet the gut he gave me another set of heads. So I have identified one set of Windsor PI heads as it is cast into the head but upon inspection I cant find any markings on the Romeo heads to readily identify them as PI's. What is the easiest way to tell if the Romeo heads I have are PI's or not?

PI kinda square? Is PI stamped anywhere on it?
