Doug's and TTI's are (imo) the two best options for his application. I just wanted him to know the differences. Doug's actually are bulkier coming off the head flange as your photo clearly shows. This is due to their old bending process. With Doug's the tubes come STRAIGHT off the flange before starting to bend vs. TTI's that come off the head flange into an immediate bend which results in a more compact design for easier installation and more space between header and inner fender. The second big difference is the TTI's are step headers and the Doug's are not. Again, the Doug's are great and I've had them on other vehicles but I prefer the TTI's when it comes to A-bodies.
