    12506 is rated 3.0 out of 5 by 2.
    Rated 5 out of 5 by from Custom Truck The Headers went into a 78 F100 Stepside with a 351 Windsor motor. I did need to cut the frame a little to provide clearance, but other wise they fit very well.
    Date published: 2016-04-15
    Rated 1 out of 5 by from Trouble fitting I could not get the starter to clear the headers even purchased a mini starter. I have a 78 Ford F-150 with a 400.

    WARNING: Motor vehicles contain fuel, oils and fluids, battery posts, terminals and related accessories which contain lead and lead compounds and other chemicals known to the State of California to cause cancer, birth defects and other reproductive harm. These chemicals are found in vehicles, vehicle parts and accessories, both new and as replacements.

Some examples of these chemicals are: lead from lead-based paints, crystalline silica from bricks and cement and other masonry products, and arsenic and chromium from chemically treated lumber. Your risk from exposure to these chemicals varies, depending on how often you do this type of work. To reduce your exposure, work in a well-ventilated area and with approved safety equipment, such as dust masks that are specially designed to filter out microscopic particles.
