What's the difference between "Black nitrided" and Inconel valves? I'm looking for exhaust valves for my next head build and FCP has these listed from Supertech.

Guys, i have spare 7A head with OEM 7A valves....I want to put this 7A head on my stroker block. What about new valves? Supertech? Is need to change intake valve as weel , or just exhaust valves? I read this topic and lot of people recommend using std size valves, because bigger valves need more modification in combustion chamber..I want to make some head porting.
