TTI hands down, Doug’s are next in line but I’ve had to dent every set(3) I’ve installed.

Thanks, dent where for clearance?

Steering coupler and drivers side torsion bar area. Passenger side was close to the t bar but I was able to tweak it a little after installation and it didn’t meet the hammer.
These were all on 67-72 cars with the biscuit style mounts. You should have a little better clearance.

Thank you
You have limited choices. The best headers aren’t even made any more.

If it's a mild small block you will be much happier with a pair of 68-72 340 exhaust manifolds.
I have Schumacher Tri-Y headers on my 73 Sport 340. Fit nice but still had to dent a driver's side tube for steering box clearance and passenger side tube for tie rod clearance.
Doug’s seem to do a little better than TTI’s on the 73+ cars with the spool mounts.
Either way, people have had to dent both TTI’s and Doug’s. It’s down to production tolerances on the headers and the cars so you have to be prepared to add a dimple or two regardless of whether it’s TTI’s or Doug’s.
The ceramic coating on my Doug’s D453’s was better than what came on the TTI shorty headers I bought, and they required just as much tweaking as the Doug’s long tubes on my ‘74 Duster anyway.

I never had one single problem with the Hedman style like Hedman, Summit, Flow Tech and all the other cheap ones. As long as your car sits at at least the stock ride height, you're good.
If my choice was TII or Doug’s it’s not even close.
The Doug’s make more power than the TTI’s every time I’ve tested them.

One thing I like about Doug's: On a manual steering 72 back a body, with biscuit type motor mounts, you do not have to drop the steering linkage. You can get them in by lifting the motor one side at a time with both mounts unbolted . This is with the car on jack stands. You have to turn the steering wheel all the way to get them in. One side all the way to the left, the other side all the way to the right. Do the driver's side first. You will need to remove the oil filter and starter though.

Thanks everyone, who has the best pricing on Dougs headers?
I'd say everyone has the same price but a friend orders stuff through a chain store and gets an additional discount like Auto Zone. And dont forget you can get uncoated Doug's and do your own finish.

My Doug’s fit very well and no more crushed tubes.

Looking at the pix on the summit site. They appear to be the old design, with the tubes below the steering gear. The tubes usually get squashed.
That's kinda why folks lean towards Doug's or TTI , better ground clearance.
Auto zone has seasonal sales on Doug's, 20 - 25% off, - other retailers, Jegs etc often price match, - some offer free shipping.
Good Luck.

Shorty spitfires/Layson's take a lot of hammer time and some pipe fabrication to work, but they're a dream after that. No low hanging tubes, no burnt wires, come out/go in easy. Welding required!

Ran TTI's on 2 of my 70' dusters no problems no need to dent anything!!!

I ended up purchasing Dougs D455 for the 74 360 dart sport. Will have starter fit problems? Just trying to be prepared..
Let us know how they fit. Take some pic's if you can.
