I have a question on your heads though, do you see much of a pickup going from the 2.00" valve compared to the 2.02 on the ls1 heads?

Using the intake will cost you a ton of low end power over the truck models, plus you would need to install the LS1/LS6 belt drive system ( the car intakes are lower and the TB interferes with the water pump outlet ). The truck intake shows as good or better at all RPM's below 5000.
The cam would be a nice combo with the heads as long as you get the CR up a tad.
