LS2+ rec ports + tvs1900 I have an LS2 CTS-V that i DD, and I've been thinking about building it to use an LSA TVS1900 s/c I picked up.
This would not be an all out build, more like a bang for the buck with some manners. I've been looking at heads and wondering which would be the better head for my build, the L92,LS3, or LSA. To complicate things a little bit I would probably run N/A on the heads (with l76 intake) for a while with something like the ls9 cam.
I've heard things like the LSA heads are sturdier, and great castings but have some air foil wings built in for FI or, hell I'm not quite sure. LS3's flow better out of the box, lighter valves than the L92s...
If the LSA's need port work to really shine, are there a better aftermarket option?

Out of those, LSAs are better suited for forced induction as they indeed came stock on ZL1s and CTSVs that had the same supercharger basically.
The other two will be just fine also at moderate boost levels, and don't sweat the details behind them...you won't notice a difference in the air foil wings or LSAs flowing slightly less.
