Default 853 LS series heads?

Can anyone help me with what are 853 heads go on? I took them off an LS1. I was told they came from Breathless. Going to put them up forsale but not really sure if these were a factory head or aftermarket?

Any help would be great, thanks in advance.

That is correct. If they are stock, they are not worth anything. If they are ported, then they could be worth a few hundred dollars.

They are ported and came off a 2001. Not to say they were the heads that came on the car new but the car had a heads/cam package and the previous owner wanted to return it back to stock. They are a complete set of heads with maybe 4,000 to 5,000 miles on them. Looking to get $200 for them.

Thanks for the info
