Dart heads - off topic (sort of)

[The Punisher]

I am like 95% sure that all world products "dart 2" heads have hardned valve 
seat inserts(all mine do). Even if for some reason you dont have the hardned 
seats installed you will have much less problem with the metal in these 
haeds compared to oem heads. Its very hard and I believe it has a very high 
nickel content. But like I said I am almost 95% sure they ALL have hardned 
seats installed out of the box. Just run a decent stainless valve and you'll 
do fine.
BTW. if you are having a valve job done, be sure to have the seats "CUT" 
instead of ground. A shop that uses a "Serdi" machine is what you want. The 
seats have a machined finish instead of a ground finish. youre valve job 
will last longer, and may flow a little better(in theory).

Just My experiences with SBC 'dart II' heads.
