I think any year old car is fine. The crowd of all ages loves them And to an earlier post, chevy only makes iron heads at the original 23 degree. They have not cast anything, of any other degree in iron. Ford has a 10 degree iron, and I think mopar has something other then the factory 18 degree. Someone will tell me if I'm wrong, but chevy casts nothing in iron other then 23 degree. Believe me, I know.
