Default upgrading to stainless steel valve?

Has anyone upgraded to stainless steel valve in a boosted engine (turbo)?
should it be done if I am boosting around 15psi daily and 20psi occassionally?

I have the block sleeved and rebuild, in case you are wondering

My opinion:
Its only worth it if you go oversized.

Lighter, which means less reciprocating mass in the valve train. You can rev quicker, and safer.

The true value of stainless valves is to be able to withstand the cylinder pressure and temperature that high boost applications experience.

For my d-series race car I am going to start building this summer I am going to use inconel valves to withstand the 30+psi.

inconel valves is the way to go. if you have high heat its the best period. that with some titanium springs and retainers are the ultimate setup but expensive as hell

This is the setup I am looking at. Is this a good setup?
I guess it's not that important for me to have them when I am running 15psi?
