Ebay headers for my Superformance?
Hello,
I am looking for headers for a Superformance Cobra. There is a set listed on eBay right now with some codes stamped on the flange... UN10262 and what appears to be a date code 11/04/12. They are listed for $899 for the set. I have a mid 900 series Cobra with a 351 with aluminum GT40X heads. Does anyone know if these heads will in fact fit this car? Is this a decent deal? Are there better options for similar or less money? Thanks for your help. |
If they are Superformance headers and specific to your engine they should fit.
Things to look at: Flange bolt spacing. Normally 2" centers around the ports, set in a straight line. Is this what your heads have? Some heads have the bolts at top left or right and then bottom left or right (opposite the top). I don't think Superformance ever built a set for this bolt layout. Superformance had at least two different tube designs. One a single diameter tube another with a slight step diameter. Neither has significant advantages over the other. The head face to header/sidepipe dimensions are all common as the same sidepipes are used for all engines. Not sure on the price as I've been out of the Superformance ranks for a few years now. But I doubt that there are many available on the used market. An aftermarket set as offered from Firefly Performance Products will cost a bunch more. I have a set of these but they are for AFR 205/225/220 heads with a 3" bolt spacing. Jim Former owner of SPF 1855 & 2584. |
Jim, Thank you so much for sharing your knowledge. My heads do have the 2” straight line spacing you mentioned. I’ll verify those dimensions with the seller.

I guess they must have been a decent deal... someone else bought them ��
