    I've not installed TTI headers, but Doug's were a breeze. This is my install

    I have TTI on my 71 demon 340 4speed manual steering they were hell to install had to undo motor mounts adjust engine alignment and redo clutch linkage install driver side from top down and pass. side from bottom up an change oil filter rotation had a friend that did dougs with a lot less problems if I had to do it again it would not be TTI's called them for help on the clutch they said Io to changed the part of the clutch I was having a problem with and it would cost more bought it and still had to make some changes to it that being said the header look good and sound great just a big pain in the butt to install if the engine is in the car.

    Last weekend I installed a set of ceramic coated long tube Doug’s on my 72’ 340 4speed Demon with power steering.

    never touched the clutch linkage but the steering linkage had to fully be removed for my test of will. Lol! I dropped mine from the top - no go. From the bottom up on drivers side- engine maxed lifted. Easy peezy.
    Passenger side was a bear. Just a note they go under the oil filter but above the idler arm....... please don’t ask. Jameson whiskey was involved. Lol!

    over all best fitting headers I’ve ever used.

      Also add- I had to cut off the small square block off my bell housing to line up with the passenger manifold ports.
