are the stock heads on a 2001 camaro ss/z28 243 or 231 heads... and are they different from 98 -00 ?

wanted to trade in my heads for a core... but they want 243 not 241 casts...

They are different from the 98-00. I can't remember the numbers, but 98 was different from 99-00, and the only real difference between the 99-00 and the 01-02 is the 01-02 has a better casting, which doesn't make a huge difference but still helps.
