Nice numbers. 
Have the heads been touched in any way at all?
Also is this through cats or no cats?
Thanks and congrats
It's a 441ci and ~560rwHP

And that A/F graph is as flat as a pool table too. Very nice.

Apparently there maybe some MAJOR gains to be had with porting the exhaust side since it's relatively weak on LS7s (comparing to wild intake side flow numbers
)Something you can always consider when you get bored
Have fun

I'm very interested in seeing the output numbers from 441/447 MDS packages which are using the LS7 heads. My results are below (sig) and reflect highly tweaked LS6 heads. At least one of our community is installing tuned LS7 heads on a Cartek 447 MDS package. I'm awaiting those results. I'm in no hurry to spend more money on this project but Dave at Cartek is predicting 50 more rwhp. If so, that would put me in the 620 range (or so) on pump gas and a streetable engine, which is what I have now.
