Default What heads did my 04 come with?

I’ve tried searching around and trying to see but I don’t know what heads came in the late model base c5s. Can anyone give me the rundown on what heads came in what years?

You can verify which heads you have by looking at the passenger side head towards the front. You will find the 3 digit casting number there.

Makes sense since the LS1 got updated in '01. Thanks for the clarification, info above updated and corrected.
