I've been to this link. Did you look at the form they want you to fill out to get a response from them by email? No where in there does it mention anything about headers. Its all carb stuff. Not sure if Holley makes Flowtech headers now or what ? Funny thing is I did call this number about a carb I'm interested in and I did leave them a message. They did return my call but I was working and couldn't answer my phone.
