MadMax SE

Im looking to buy some headers but i just have to be sure i have my info right. I have a 2000 se with four o2 sensors, if i buy headers would i need a version with or without the egr port? I know the federal versions used an egr valve on the exaust on the 2000 fed max and a few older years aswell, the 01-03 didnt, i believe there cali spec. This is where im stuck, im unsure if i have an egr port on my stock precatted manifold being that my car is cali instead of federal emissions.
