Headers on my 68 Dart

Agree, I agonized over headers as many that were supposed to fit well definitely
Have a high frig factor. After much research i found was that you pay for what you get. Not only are cheaper sets have high ffrig factor and and poor quality welding and not so good coating. Go ahead and get Dougs I haven’t heard anything bad about them and have been told they last longer and have superior raw materials and craftsmanship
Just my . O2 cents.
