I have four sets of iron heads being done here at the shop right now, and another set on the way.

Iron still lives on!!

3 sets need to be iron for what the owners are doing with the cars, another set doesn't "have to" be, but really "should" be....... The last set, they wouldn't really need to be, and if it were my decision, I'd probably use stealth heads on it, but the car owner wants to use the original heads.
