I've been looking for a set of PI heads. I've found a couple but the casting numbers differ from each other. I've seen some that were 1l2e, xl3e, 4l3something. What exactly are the differences? Is one better than the other? I have a 98 gt with a romeo which I believe is a 11 bolt valve cover. Does that mean I should buy pi romeo heads? Maybe someone could guide me in the right direction. I found a set on ebay that are 1L2E castings but have no clue what is better than the other.
Thanks
Bill
