When I posted this the last time, the resolution was all screwed up. I have gotten that fixed, so I am posting a version you can actually read.
The second sheet is a sheet of only LS6 heads..
All cylinder heads LS1, LS6, 6.0, and 5.3
LS6 flow numbers only

hmmmm for some reason, I can't get the image to come up. Anyway, the link is in there. You can post it into a browser if you like. I will work on trying to figure out why the link doesn't work

The link doesn't work because there is an extra right bracket in the URL, just after "jpg".

This is some great info, but a couple questions. Were these all measured on the same bench? I'm kind of puzzled why the stock LS6 heads just marginally performed better at higher lifts than the stock LS1 heads. And then the Andy @ AA stock LS6 heads flowed alot better than the stock LS6 heads in the 3rd column, different flow bench or what's the story there?

yeah the andy numbers are interesting.
Not to knock him. The 6.0L can flow that much if done right but his bench seems to read high anyways. If that is the case, then I don't know what to say about that. Just take 10-15cfm out of the numbers to get what another bench might say.
Who knows though, the other benches could just be down.
