difference...n heads?
Patroit has their name carved in the side of their head.
If they are PP and they aren't 5.3 heads the casting number is normally scratched off the head. If there the 5.3's then I imagin the casting number would stay on.
If the Patroit name isn't carved in then it probally isn't Patroits head as they have been doing this for some time now.
Also PP spring have a gold tint to them but again if these are used then the color might be hard to tell.
