Unusual T/A

I'm looking for the actual differences between the two styles of heads on the 99 ls1 and the 01-02 ls1 heads. I believe the 99's were the 896 and the 01-02's were the 241's. I need to know the cc of both heads. If anyone can lead me in the right direction i would appreciate it!

THanks

Sweet so what i gather is that the 853 and 241 have the same amount of compression. But the 241 flows better?
