Dynamometer Results & Comparisons - ls1 with 5.3 (706) heads

I'm looking for anybody that has stock 5.3 heads on there ls1 with a cam. Just want to see some number on this setup. I know i should get them ported but i don't have the money to do that right now just putting them on to get up the compression since i was told they don't flow much less than stock ls1 heads.

Let me know what you guys think about this setup
