Ok, I done it now…!
There has been some talk about this header so it tried it:

I bought the uncoated 6 into 1 header from mustangs unlimited.
I put it in my '65 stang that has a 250 in it.
I was able to bolt it in but the collector flange hit the bellhousing.
(jahearne told me it would so I ordered the uncoated ones) (thanks)
On to the remedy:
With it bolted up solid, I wedged a little bit of a screwdriver between the collector and the bell, heated all the pipes using a blue-tipped hatchet and let it cool slowly.
I then repeated once more after wedging the collector out a little farther.
It really looks like it worked.
It needs to take a trip to the muffler shop to mod the downpipe (unless I can make that work too)
I am not RECOMMENDING this to anyone, just saying it can be done.
Another solution is cutting a pie shape out of the outboard side of the collector, pushing it together and welding it up. It would give the collector tip a "kick-out"
Not sure if I can get good pix, but I will try if someone wants them.
also: I e-mailed Mustangs Unlimited to let them know it does not work on a 250 but if they could get the supplier to kick the collector out 1/2" it would...
