Can someone give me some background history of the Stage Jr. heads. I now own a set and I am wondering where they came from, why they aren't in any literature and whether they can be ported more than production heads. I know you can port out the Stage 1 heads because they are beefier in the ports, is this true with the Jr?
Please educate me and anyone else interested. Thanks!
