We just put a set of these in a 75 duster, 383 auto, eddy heads with ps, spool mount V8 k frame, Schumacher motor mounts. A few of the problems we had were passenger side #2 tube hit inner fender, had to dent between shock bolt and engine along the edge of inner fender. #4 or #6 tube hit engine block along oil pan rail. Had to dent tube for clearance. Another spot was the driver side inner tie rod, pitman arm hit, also has to dent the tube. This is only an issue on the 73 and up a cars. The early pitman arm center link will clear. We had to move the brake lines from the master cylinder to the proportioning valve.
Some of the bolts are very difficult to get in as well as a few of the spark plugs. The B motor is an 1" or so narrower and 3/4" lower this creates a few challenges. They are great headers, very well built, they need a little work to fit right with this combo. Follow the installation instructions and the cutout templates will get you in the ball park. Expect to spend a good day on each side.
