I have those exact headers on my '72,only I bought the non-ceramic coated and had them coated locally. None of us knows for sure how those deep scratches got there,but I assume Capt Fab saw pictures first and those scratches weren't there. Mine went in pretty easy. Easy enough that I can't imagine anyone scratching the tough ceramic coating through like that trying to install them. It would take a sawing action over and over and over again. I can see how those cuts could be made from the edge of a flange being up against that spot and shifting back and forth. There was not even a bag over these headers from the way I read it. I have other ceramic headers I have yet to use still in the bags they were shipped in and they are fine.
Whenever I have sent parts in the past I've been concerned they make it unharmed. It would be a nightmare to have an issue like that. You have the money,the buyer has a damaged part. Nothing like selling a part to end up owing money. That's why you go over and above to pack a part the best you can to assure it arrives in the condition it left in.
