Hopefully all those things will be available for the LS3/L99.
Can anyone give some insight to the hotcam vs high lift rocker option? Do you think the high lift rockers will add anywhere near the power as the cam? It's just such a simpler mod than a cam swap if it's within 20 hp it might not be worth it.

The rockers are a waste. They cost more than a new camshaft and require new valvesprings. Overall, you're looking at about $1100 for the rockers, and valve springs/retainers. And you might see 10 rwhp. Not worth it. Go with a cam.
