Just curious if anyone knows if these would fit the mn12/fn10 chassis and not hit the steering column. I know I can joint the steering shaft but then I might as well buy Kooks longtubes and this isnt an all-out engine swap that Im doing (1995 thunderbird) I am considering buying those header flanges they have on ebay and making my own.

They will physically bolt-up, but you may have clearance issues with steering, etc. Just go with the Kooks 3/4 or longtubes and be done with it...

Shorty headers won't give you more than 5hp anyway...

well Id have to disagree on the 5hp comment. Obviously the kooks are the way to go I already mentioned that. But my 95 is not my project car, it's my daily driver, I only came into the DOHC engine swap because my SOHC blew a headgasket. And the log manifolds look like crap.
