Not sure I understand what you are saying.
BPE making the heads for themselves. They are making them for the public. Guys like me.
In fact, Rod I believe is in the middle of a Gen 3 build to put in a project car he is working on, has nothing to do with the heads he sells.
The BPE heads are for someone who wants the best performance available in a non offset head, by a significant amount.
They aren’t for everybody, many would be perfectly happy with a trick flow head or some other choice.
