Hey red, that was almost helpful. I have the stock heads on (well, not really, they're beside my car right now) my car and they have the GT and 3 vertical lines, and they are stock Cobra heads. I guess that would make them GT-40's. Although I don't know if they are the GT-40P heads or not, or if there is even a difference. It really doesn't matter though. Neither are AFR 185's, or TFS High Ports.
Later.
