351c 4v headers

I have a 70 mustang fastback with 351c 4v with C6 can someone tell a brand of headers that will fit this combination. Brand and part number would be great.
Thanks

Did you ever figure out what you need??? If not try Hooker Super Comps. Maybe you could call their tech line for a better idea, but I've seen them suggested before, so maybe they'll help here.[img]/phpBB/images/smiles/icon_frown.gif[/img]

I'd take a look here. http://www.fordpowertrain.com/FPAindex/headers1.htm

I'm going to be using these when I swap a 351 cleveland into my 69 mach 1.

I used the FPA headers on my '72 4v 351C. The headers are super thick, and are made specifically for the 4v heads. Despite what the other companies claim, only the hooker super comps and the FPA's truly fit the 4v heads (you'll have a serious gasket leak that will develop on the others - I've used them all). The FPAs are easier to fit than the other brands, however, I had some adjustments to make (as can be expected with headers). Lakewood bellhousing had to be slightly ground and the header pipe dented; I had to grind a bit of weld on the collector, and add a spring to hold up the zbar to keep it from vibrating against the collector pipe, and a good bit of beating on one pipe on the passenger side to clear the motor mount (these headers really hug the block). Nothing unexpected, and the quality is top notch.
