I am thinking of adding the GT350 heads+cam to my 5.0. What is the expected gain from them in terms of torque and hp? I only use my car for the road course.

The cams won't work due to the different crankshaft.

I'm pretty sure that he means the required Ford Performance cams made for using Voodoo heads in a 5.0L cross plane configuration.

I read about doing that swap recently, besides the heads and the Ford Racing cams specific for that application, you also need the GT350 rocker arms. It ends up being a very costly exercise, and if that is the only change you're making I can't imagine the power gain would be worth it.

I think your money would be better spent on a comp cam setup using the Gt heads, if you’re wanting to stay strictly N/A

If you can’t get your hands on a set of affordable GT350 heads I’d use the 15-17 5.0 factory cams with MMR rocker arms on the GT350 Heads and Intake manifold.
This combination is plug and play on the 15-17 5.0 Coyotes and retains fully functional IMRC.

Power output should be close to the GEN 3 Coyote.

It would be a lot cheaper to port 5.0 heads and you will gain about the same power as gt350 heads
