Installing headers 73 duster 318

Don't get offended when you see stuff like this up there. Once you put headers in an a body you will understand. lol Not directed at you just in general.
If you see your comments are a mistake , next learn from it. Most of our knowledge is learning from mistakes and by the help of our great members. Just my 2 cents.

What the heck does that mean? I've been around awhile and have plenty of experience with these cars. Hooker headers are only barely better than Hedman. They are poorly designed and a pisser to install.
