340 drivers side exhaust manfold question

it goes up to clear steering. I've seen people put rear exit low manifolds on a bodies but they always rubbed everywhere.id stick with a body manifolds and look into having yours fixed or find another one. you can usually score a nice 72 up driver side reasonably cheap.if the one you have is a 318 I'd toss it and get another....preferably a 340 set.

also check your heads, if there 587 castings early manifolds will not seat properly...could just be a gap causing the noise.
