Would make sure to check PTV clearance to make sure the valve reliefs in the pistons match up ok with that cam. Shouldn't be an issue but worth checking. LS3 heads respond better to high lift over duration.

Motor: LS2/402, Eagle crank/rods, Mahle pistons, Dart Pro Heads
Cam: Crower 622/609 238/246 112LSA (may change to suit LS3 needs)
Car: 2003 C5Z06
Tuner: Don Kinder has been tuning my builds since 2006
Why? Dart Pro's, I know nothing about them, but have been told(key word here) that they are just above 243's
Plan: remove the Dart's and install the LS3 heads(take-off), the LS3 intake/90mmTB cost is not an issue(the LS6 intake would cover it if sold)
1. LS3 heads($600)
2. LS3 intake/90 ($300-400)
3. Cam ($350)
Thanks for the info

The engine in the link above has ARH headers you all made for me last year. As for your cam, I think you will find it will work great assuming this is 11.5:1 or less on pump gas and you degree it in on a 109 or 110 degree intake centerline.
