I had some dome fitment issues with the head I bought from those guys, to the point I sent it back and let them keep it. As it turns out, some of their early heads had some anodizing related tolerance issues, but that has supposedly been fixed.
Their chrome heads still don't work correctly when it comes to this issue, but they know about it and I gueess they are try to fix it. However, they are still selling the chrome heads which makes you scratch your head a bit. :geek:
