For a standard LS1 head those dont look to bad over stock. If they are a stage 2 LS6 head I might be making a call to the person that did the work, but thats just an opinion

Here are the results for my heads, just as a comparison.

Only thing I see that is a little odd is your exhaust numbers seem to be a little low.
