Yes they will fit the 351M. What vehicle do you have? The only issue is what vehicle you have. Most 351C applications are for cars and not trucks.
I found this as well...
Exhaust headers � Several companies that make exhaust headers offer headers for the M-block engine in Ford truck (and Bronco) applications. You can get both 4-into-1 type headers and Tri-Y (2-into-2-into-1) headers for the M-block.
Actually, since cylinder heads are interchangeable between all 335 series engines, any header designed for the 351C would bolt up to an M-block. The suitability of any particular header might be determined by its fit in a particular vehicle application (i.e., clearing the starter, engine mounts, frame rails, crossmembers, transfer case, etc.).

using C headers on an M engine will move the collectors up nearer to the floor boards, and make the pipes crossing beneath the crossmember tighter as well. the heads sitting on an M engine are higher up in the chassis than where the heads of a C engine sit. not a lot, but some.
