FS: Supertech valvetrain - dual springs, titanium retainers, and valves
I'm not sure. Is they're a way to tell? It doesn't have the black nitride coating like the intake valve on the right does. It just looks more like a stainless steel.
Thanks for the bump!

Inconel valves don't have any coating on them so they just look shiny silver. Are the black markings on them carbon build up? If so, then it's possible it can be inconel. I know the black nitrate doesn't easily come off.
Just checked and the only options are black nitride coated stainless steel valves, or non coated inconal valves. This means the intake vavles are stainless steel and the exhaust valves are inconel.
