Who makes the BEST ceramic coated headers for the 351m\400 engine---I have a 77 f250 hiboy and am having trouble finding a good set of shorty headers----would like to keep all the heat in the engine and exhaust----thanks for your time , fordlover

 

I know that dynomax sells a good full length header, for cheap, about 200$ it is jett hot coated inside and outside. I dont know about any shorty headers though.

 

Sanderson makes 3 different styles of block hugging shorty headers for the Cleveland motor. They should fit the M heads too but you probably ought to call them to verify. Here's their website: [link:www.sandersonheaders.com/enginetype/appbyengpage.htm|Sanderson Headers]

 

Bill , thanks for your help as well as the person before you --I don't want a full size pair of headers. 1977 hiboy ford trucks seem to be a problem for alot of manufacturers---I don't understand why---but I have encountered this situation many times---Probably a volume situation--not enough sales , sandy kuteman
