interchangable headers on a 351M/C/W
hey im wondering if headers or manifolds for a 351 cleveland can be interchanged with a 351 windsor or modified, and visa versa. are there any differences in either the block or the header shape themselves that will prevent me from swapping? the headers im trying to get fit a 351 cleveland out of a mustang fastback. a buddy of mine has a set laying around and thats why im asking. i wanna know if theyll fit before i take everything apart and they dont line up.

On my 79 2WD with the 351C I tried 2WD 351M headers and they hung down way too low to work.A set of Must Clev. headers would have worked without the x member between the radius arm mounts.They would have worked with a fabbed xmember wich wouldn't have been hard to do but I was building a driver so I used manifolds.A friend of mine has a 351W in a 73 2WD with Must. headers and just left the x member off.He just cruises to shows so it's OK I guess but I wouldn't want to use one a lot like that.
