I am in contact with a local seller who has a set of what appear to be Hall Pantera Headers, the price is very reasonable and the seller seems like a nice guy.
He sent me a photo of the flange. To my surprise it has a round aperture that matches the 1-3/4" diameter primary pipes. I expected the header flange to match the larger cylinder head opening rather than the smaller pipe.
Am I mistaken in thinking this would have poor flow characteristics and kill performance? It seems like this would be as much of an issue as my 2V flanges.
If I am misunderstanding this please explain it me, I am totally new Clevelands and I don't fully understand what they need to make power.
