Best exhaust manifolds???

The 340's fit my 65 23 years ago but I remember they were ground a bit on the driver side due to my power steeirng, but my oil soaked motor mounts back then were about as soft as sponges so there might have been some settling or shifting ( I think I even had the later 67's, not the 3" thick 65's) . The early Dakota's are supposed to be the ones to beat and at $50 a set, really hard to beat! Lots of debate on whether they are drop ins, but they look to be close enough to make work.
