Did I miss something? How do you get these? How much? If I search BPE heads all that comes up is a shop in California. Any details about vlaves, guides, springs? or is that a custom thing and they come bare?
Also I saw you designed these for a 400+ inch engine, how would they do on a 360? I don't really need or want a stroker currently.
EDIT: I found this on Facebook, I'm assuming this is the old version?
