Unless your heads are listed in the program (and stock LS1, much less ported LS1 heads are not) you need to know the flow rates of the head across the rpm band (and I have that data).
And the peak rpm points are not accurate. Probably because it doesn't take into account the weight of the reciprocating assembly and valve float. So I just go by what the numbers are where I know my engine actually peaks out, at around 6K. And it's much more accurate that way.
I can send it to you if you want...

The peak should be higher than 6k with that cam. BTW, I'm pulling my cam this week-end (242/248/110) and going to a 230/236/114. My off-idle torque and fuel economy were really bad....
