To set the record straight so that your statement doesn't get out of control. There is "NO" header out there that I personally built that has a fitment issue for the 2nd gen birds/68-72 A-body's. No matter O-port, D-port or RAV's. Thats because I go the extra few minutes to check "EVERY" header on special test frames that are always positioned in my shop before they are boxed up. Even though my jigs that I had modified for them have't yet caused any fitment issue to date. I do it only because of a few fitting issues with a past header Co that cost me $1500 before they fessed up to it.
When I made the patterns for the 64-67 Abody's years ago it was done on a friends 67 Lemans I had at my 1st shop. They fit fine & only after I sent out all the O-ports I found that one collector barley touched the lip of the trans pan. The customer that told me about it said it was a non issue for him since he just bent the lip a tiny bit. I wanted it to be as perfect of a fit as possible so In the years since I have I had slightly changed the position of at tube & the angle of another to make sure the problem wouldn't happen once they were made again. I did this off the car & knew at some point I would be able to check them on a car. I never gotten another 64-67 A-body to check.
This is why the first person to get that style header was located 20min from me. Know full well that if there would be a problem I could easily fix the problem from such a short distance. Little did I know that it would take months for him to install them while I eagerly waited for any news. All the while I had gearbanger on my heals for them. I built a total of 4 sets & just before shipping them out I heard of the issue from that customer because he had just installed them. I arranged with SD421 to go help him through the work of installing a block, heads & trans into his GTO to fix the problem. He says 3-4 trips I think it was 4-5 trips but either way it was a 40mile round trip each time. The problem is fixed & is a much better design. As for the starter, a stock starter may fit but would be to close to last long at all & wouldn't be an easy R&R. So all sales will have a footnote stating that (its not at all uncommon for a header Co to list such fitment footnotes) a mini starter is required. At a later date when I get a 64-67' A-body at my shop I will make the necessary adjustments for a stock starter.
