Pros and Cons of each? Going in my 02 Camaro SS M6.
From my limited research, it looks like the LS3 heads are flowing very well, but my understanding is you have to use the GM intake. Well, I have a FAST 90/90 that was used for a month before my motor went south and I don't really want to sell it.
If I do the LS2 I'll be opting for some TFS 235s most likely.
My goal is ~520-530rwhp and 500rwtq with a good power curve. I don't really care about peak HP I just want torque and a smooth curve.
Also might be adding nitrous in the future.
Should I build a 402 LS2 or go for the LS3?

Will the Trick Flows bolt up to the L92/LS3 block?

I've looked at TSP and Weber Racing, they are within a few hundred dollars difference on the two motors.
Going with Wiseco pistons, either Callies or K1 Tech crank and rods, ARP bolts.
Is the 14-16ci worth ~$500?

Bigger is always better, so IMO yes the 4.070 bore with the 4" stroke is worth $550 over the 4.005 bore and 4" stroke. If its a breaking point the 403 is a great way to go but if you want more power then a bigger engine is a bigger engine and will have potential for more power.
I can produce a version for $250 less using a Scat crank and Eagle rods as well, I like to use Callies where I can and the customers budget permits it.

I'm going to stay away from Eagle. Callies is my preference with Wiseco pistons.
If I decide to put nitrous on it later I want to make sure the 418 can handle it. I don't want to be on the edge either, building a new motor isn't something I want to do more than once out of necessity.

I went with ETP heads and a FAST 90, but I am also an auto.
500 rwtq is going to be difficult to get...
With that said the advantage of the 416 is clearly in the torque department. There are some 402's out there making close to the same HP but lacking the torque.
I have not been able to run the N20 yet, ran into some frustrating issues with the install that is being worked out now.

Ok now if I decide to go with the LS3 based motor...
Keep my FAST and get cathedral port heads?
Get ported L92 heads and ported L92 intake?
Either way it would come out to about the same amount of money. TFS heads will run about $2500 and then I'd get my FAST ported.
Or ported L92 heads for $1300 and ported L92 intake, sell the FAST.

When you sell the fast you will be less expensive in the end.
Honestly, It is 6 of one, half a dozen of the other. For what you want to do, either combo will get you there.
