No problem, spitfires. They are shorty headers. You can find them here the odd time or on ebay. They were made by a one man shop in Arkansas but I think he is out of business. Laysons sell a similar header. For a more serious motor in an early A, I would invest in a set of TTIs or go to a good fenderwell header if you don't mind cutting your inner fenders. These 273s were pretty choked in the exhaust department with the log manifolds so a header seems to make quite a difference.
