Welcome all. I just recently had my 250 l6 from my 66 Chevrolet Bel-Air rebuilt and was wondering if anyone had any experience with either of these headers. According to their site, i would be required to use the shorty's because of having an auto with a column shift. I also wondered which intakes would work with these provided i went with a water heated intake. Will either/both work with a stock or offy 4x1 manifold? I'd rather not use the clifford intake cause i like my torque and the clifford is a little big. Any response would be greatly appreciated. Thanks!
