I tried to search, and I couldn't find a good answer.

I have a BP4W head fresh from the machine shop.
It has Supertech dual valve springs and is otherwise stock.
The stock valves were all in good shape, so they were reused, and just lapped.
The head is all shimmed, and ready to go on.

Would I be better off to get some inconel valves for the exhaust side before it goes on?
If the work wasn't already done, I would definitely get them for peace of mind, but I don't know now.

Boost will be supplied via a GT3076r, and I have no plans to rev past 7800 or so.
The car will see some track time.

No reason to swap them if you built your head already, unless you just like paying double for Assembly/machine work
