Eh? There are many header combo's for a 351/fmx...
I run Hooker Competition headers. Hooker part number 6901, or ceramic coated part number is 6901-1
Or, the Hooker Super Comps, which is part #6116 or ceramic coated part 6116-1
Hedman headers part #88300 too...
That's just off the top of my head. I like the Hooker Comps, but the super comps are lighter and a bit longer, but cost alot more.
Anyway...
