ls1 flow numbers

Does anyone have flowbench results on stock 98 ls1 heads? I've searched for them, can't seem to find them.

Here's some #s comparing heads on a thread over in the Gen III internal engine where a NASA racer is wanting to downgrade his heads to meet the required power levels. Here are his #'s. 806 is the '98 head IIRC.
